Four SCMs cored after a switchover.

Impact: The SCMs have cored after a switchover.

Root Cause: There is a bug that allows the RTM to attempt to process the Call Audit fault, while still in STANDBY mode. The Call Audit fault will only be processed while in Active Mode. This causes a core.

Steps to Replicate: The steps cannot be reproduced.

Platform/Feature: SBC

The SCM fast memory increase caused a delayed switchover with an outage.

Impact: If the multilevel INVITE with Replaces is run, memory and CPU utilization by the SCM Process increases drastically and leads to core dump.

Root Cause: Each INVITE with Replaces is a new Callgroup. Each call group has their own segments. For each segment, there are associated segments.

When the Release call is invoked, it releases all segments and each call segment frees associated call segments. During the release, the flow for such a call event is posted multiple times for various orig and term GCID’s.

Steps to Replicate:

1. Test multilevel INVITE replaces (more than 15)
2. Crash should not occur

Platform/Feature: SBC

The code is modified so the event does not need to be posted multiple times for the exactly same original and term labels.

Portfix SBX-97129: After an upgrade to V08.02.00-R001, the Inbound Teams DDI call placed on hold causes a core dump.

Impact: Getting a Pes Process coredump while running registrations.

Root Cause: The CallParamMatchName function is called with a matchName, which is a 15 byte array and the strncpy is used to copy the string to the 50 byte array but with a wrong size of MATCH_NAME_SIZE, defined as 30 byte*.*.

Passing a bigger size than the actual destination string to the strncpy is resulting in padding 0’s beyond the actual 15 bytes of the matchName. This was corrupting the stack and the stack pointer, causing a segmentation fault.

Steps to Replicate: The steps cannot be replicated.

Platform/Feature: SBC

The Edit route action taking a long time to complete.

Impact: The Edit Route action was taking long time and failing.

Root Cause: Use of special characters, such as # in destination National field, can cause the failure of the Edit route action.

Steps to Replicate:

1. Create Route with special character in Destination National.
2. Select the Route that is created in Special Character.
3. Edit Form must be load.

Platform/Feature: SBC

A few more special characters to support Destination National field in the Edit route are allowed.

NOTE: The following special characters are not supported: & = , \

After the LDG triggered a switch over, the SBC is rejecting all register messages with an 500 internal error.

Impact: The SCM process may coredump when the SIP signaling port being used during a SIP registration call flow is state disabled.

Root Cause: The SCM process core dumped when it attempted to display a debug warning message that contained the disabled SIP signaling port number (but encountered a NULL pointer).

Steps to Replicate: The steps cannot be reproduced.

Platform/Feature: SBC

TLS call failures were observed due to a port value set to 1 instead of 5061.

Impact: The SBC uses Port 1 for sending an INVITE out for the TLS protocol when the route header was received without a port.

Root Cause: The issue is because when the route header is received without a port in it, the SIPSG was incrementing the port for the TLS. Since the port was not received, the port received is considered as 0. For the TLS, increment by 1. When incremented, the port becomes 1 and this gets used for send an INVITE that is resulting in calls failing.

Steps to Replicate: Send the Route Header without port Route: <sip:ipaddr:;lr>. The SBC will use port 1 for sending an INVITE that is causing the issue.

Platform/Feature: SBC

The code is modified to check when the port is received in route header or not.
If port is received, then increment the port for the TLS. If it is not received, then increment and allow the SIP stack to handle it.

SBC is not sending RTCP to egress Peer for transcode only.

Impact: In customer call flow :

Ingress Peer -(ISDN)> GSX ---(GW2GW)-> SBC --(SIP)-> Egress Peer, with PSP setting as "transcode only" and RTCP enabled, SBC does not send RTCP packets towards egress.

Root Cause: Due to changes made for feature SBX-6366, SBC does not mark XRES resource as duplex and marks it as receive only. And hence SBC does not send RTCP towards egress.

Steps to Replicate:

1. Reproduce the problem in following call flow:
   Ingress Peer -- SIP -- GSX -- GW2GW -- SBC -- SIP -- Egress Peer
   This transcode only call and RTCP is enabled.
   Result: No RTCP sent by SBC to egress .
2. Verify the issue by applying SamP with GWFE change but not change in ScmP. ( just debugging logs )
   Same setup.
   RTCP traffic was sent from SBC to egress.

Platform/Feature: SBC

The SRV query is not sent to the DNS server when porting the SBX-86420 fix to 6.2 and 7.2 code branch.

Impact: In this case, even when the FQDNPort is zero, the SIPSG/SIPS port is incremented by 1 so the FQDN port is set 1. Due to this issue, the SRV query is not sent to the DNS server.

Root Cause: When the TLS tranport is selected, the SBC is trying to increment the FQDN port by 1. In this case, even when the FQDNPort is zero, the SIPSG/SIPS port is incremented by 1 so the FQDN port is set 1. Due to this issue, the SRV query is not sent to the DNS server.

Steps to Replicate:

Procedure:

1. Send an INVITE with TGRP parameters in R-URI.
2. The SBC sends TGRP information to the PSX.
3. The PSX does TGRP based routing and sends the route.
4. The SBC will send a SRV query to the DNS to resolve port and ip details when egress peer is FQDN.

Observation: The SBC does not send SRV query to the DNS but sends 'a' query.

Expected: The SBC will send a SRV query to DNS to fetch port and ip details and establish TLS connection. with peer.

NOTE: The same scenario works fine when the egress transport preference is UDP or TCP.

Platform/Feature: SBC

The Backup/Restore file cannot be downloaded from the EMA if the file name contains a dot (.).

Impact: The Backup/Restore file cannot be downloaded from EMA if the file name contains a dot (.)

Root Cause: The issue came from the downloadSavedConfig block making an API call while running the SBC and running on the EMS at the same time.

Steps to Replicate:

1. Login into the EMA.
2. Navigate to Administration -> System Administration -> Backup/Restore.
3. Download the Backup file.

Platform/Feature: SBC: EMA

Caller eSBC cancels the call after 180: 504 to ingress, CANCEL to egress.

Impact: Late media convert call with DLRBT is not working.

Root Cause: Bad resource activation.

Steps to Replicate: Setup a late media convert call with DLRBT enabled.

Platform/Feature: SBC

The SBC IgnoreTransparency cannot be set on the EMA V6,7.2 and 8+.

Impact: The SBC IgnoreTransparency cannot be set on the EMA V6,7.2 and 8+.

Root Cause: There was no check if the "not" is applied to complete expression or not.

Steps to Replicate:

1. Log on the EMA.
2. Navigate to All-> profile-> services-> Transparency profile-> SIP Header
3. Select transparency profile.
4. Click on New Sip Header.

After that, the "Ignore Transparency " field can be seen.

Platform/Feature: SBC

Disabling the media lockdown does not suppress media lockdown re-INVITE when the SRTP is enabled.

Impact: If the SBC offers crypto, and peer does not reply with crypto in the answer, a re-INVITE is sent to lockdown the crypto attribute (no crypto ). If NAT is enabled, one second media drops while re-learning for the new re-INVITE is happening. For non-NAT cases, nothing will be observable except for a signaling change.

Root Cause: The issue was the SBC's original behavior.

Steps to Replicate:

1. Setup the SBC so that it sends crypto in offer.
2. In answer from the peer - do not send any crypto attribute.

Without fix, the SBC would send yet another re-INVITE if fallback to the unencrypted is allowed. With a fix, this extra re-INVITE will be suppressed.

Platform/Feature: SBC

A SIP to SIP call no ring back tone passed into the ingress when the PEM header is enabled on the egress endpoint.

Impact: There is no RBT when the PEM header is enabled, splitting 18x into alerting and the progress flag is enabled.

Root Cause: This flow was never tested with a flag or split 18x into alerting and progress.

Steps to Replicate: Setup a call with PEM enabled on the egress and with the split 18x flag enabled.

Platform/Feature: SBC

The SMM writeCdr was failing to write to the ATTEMPT CDR when acting upon the 300 Multiple Choice.

Impact: The SBC is failing to write the SMM fields in the ATTEMPT CDR when acting upon 300 Multiple Choice.

Root Cause: The code was missing to handle the SMM information for a Redirect Scenario in the CDR.

Steps to Replicate: Use the SMM to write in the cdrField1.

The information in the SMM will be correctly written, but will not transfer to the ATTEMPT log.

Platform/Feature: SBC: CDR, SIP

Unable to change the Source Port to any on the EMA, IPAccessControlList screen.

Impact: Unable to change the Source Port to any on the EMA, IPAccessControlList screen.

Root Cause: The source port attribute is validated as an integer instead of an alphanumeric.

Steps to Replicate:

1. Bring up the SBC in 7.2.2R0.
2. Log on to EMA.
3. Select 'ALL' -> 'Address Context' -> 'IP Access ControlList' -> 'Rule' -> 'default'
4. SourcePort is not changing from integer to 'any' in EMA.
5. It working fine in CLI, SourcePort number is changing from integer to 'any' and 'any' to integer.

Platform/Feature: SBC

The ImPr cored when the SBC was running a call load.

Impact: The SBC ImProcess cored when the LI server became unavailable.

Root Cause: When the LI server becomes unavailable and a large number of packets are queued up for that server, the ImProcess takes more than 10 seconds to clean up all those packets, and the process core dumps.

Steps to Replicate:

1. Establish a large number of LI calls.
2. Bring the LI server down.
3. Ensure that the ImProcess does not core dump.

Platform/Feature: SBC

Portfix SBX-96834: Asymmetric PRACK Interworking was not working as described.

Impact: Whenever any codec entry is deleted from codec list in the PSP and in the PSX, it rearranges the codec list immediately. There will not be any empty codec entry in the list.

The same issue is in the ERE, so it can be treated as a bug in the ERE.

Root Cause: When any CodecEntry is deleted, it is not rearranging the CodecEntry, which causes a NULL value in that place.

Steps to Replicate:

1. Configure the CodecEntry1 ,CodecEntry2 to CodecEntry12
2. Delete any CodecEntry.

Result: The call will be successful.

Platform/Feature: SBC: ERE

Portfix SBX-96706: Multiple switch overs causes non 5060 sipSigPorts to become inactive.

Impact: When user configured >= 2 SIP SIG ports are configured with same IP address but different port numbers, they are using the same LIF group that contained 1 LIF.

Pkt down triggered a switchover and it stayed down for an extended time. After the pkt up, a second switchover occurred, then only one SIG port became inactive. The other SIG ports were stuck in OOS.

Root Cause: Since the pkt port was down when new standby node came back online, the SIP SIG ports were restored while the LIF was OOS. The address registrations failed as a result. After the SIPCM has reached max number of retries, the LADDRs of the SIG ports, except the first one, were deleted in the NRS context.

Later when pkt port came back up, the NRS brought LIF back in service and registered the only one signaling address saved in the NRS context.

Steps to Replicate:

1. Configure the 2 VLANs on YF or BF pkt2.
2. Configure the 4 SSPs on the first VLAN interface; 4 SSPs on the second VLAN interface. 4 SSPs use udp/tcp port numbers 5060, 5160, 5260, and 5360 with the same IP address.
3. Run the sbxstop command.
4. Unplug the packet ports - YF pkt2.
5. Run the sbxstart command
6. Display the SSPs on VLAN interfaces.

Platform/Feature: SBC

The code is modified to only delete the LADDR before reaching the max number of retries. And restored the pendingNrsReq flag properly when the address registration failed.

The SBC Memory shows High alerts.

Impact: When Local Ring back tone is configured on the SBC and egress endpoint sends 183 Session Progress with SDP followed by 180 Ringing, SCM Process does not free up memory allocated even after call is completed. Without a fix, SCM Process will leak memory.

Root Cause: When Local Ring back tone is configured and egress endpoint sends 183 Session Progress with an SDP followed by 180 Ringing, SCM Process does not free up the media session descriptor structure.

Steps to Replicate: Run call load with a Local Ring back tone configured and monitor the virtual memory usage of ScmProcess. With a fix, virtual memory of SCM Process must not be high after all the calls have been disconnected.

Platform/Feature: SBC

The SBC releasing the call with 504 when the DLRB and Downstream Forking are enabled.

Impact: The SBC releasing the call with 504 when the DLRB and Downstream Forking are enabled.

Root Cause: The Race condition was not handled properly. When the first 180 without SDP is received, the forking list was updated and the message stored. When the 18x with SDP is received a second time, the forking list must be updated and store the new received 18x.

Steps to Replicate:

Send RTP before sending 180 Ringing.

Without fix - call is not successful and with fix call is successful.

Platform/Feature: SBC

MS Teams call flow for hold/resume then transfer causes a SCM crash.

Impact: When the music on hold is used in the deployment and a call is put on hold/resumed and then transferred, causing the SBC to coredump in the SCM process.

Root Cause: The SCM process was de-referencing a null pointer.

Steps to Replicate: The music on hold is used in the deployment and a call is put on hold/resumed and then transferred.

Platform/Feature: SBC: MS Teams

Losing a call from MS Teams, and audio loss for 30 seconds during a switchover.

Impact: If there is an SBC switch-over after the call is established, there can be a delay (e.g. 30 seconds) when re-establishing the media from PSTN to the MS Teams direction.

Root Cause: The stored SSN value does not get updated before the SBC switch-over occurs, and it causes the SSN jump backwards after switch-over, which causes the one way audio issue for sometime until the SSN value increments pass the previously sent value.

Steps to Replicate: MS Teams to PSTN call flow with the DLRBT enabled on a software SBC. Perform a switch-over after the LRBT is played and check there is no one way audio issue.

Platform/Feature: SBC: MS Teams

The DFW1-CASBC-02 Box A had a SCMP coredump.

Impact: The SBC cored when accessing Box A, switching over to Box B instead.

Root Cause: Enabling the SDP transparency and the directMediaAllow to show a simple 18x response from the peer may cause core due to access from an invalid address.

Steps to Replicate: Disable either the SDP transparency or the directMediaAllow.

Platform/Feature: SBC

There is a possible slow memory leak in SAM process while running GW-GW calls.

Impact: A possible slow memory leak in the SAM process.

Root Cause: The GWFE is leaking a copy of incoming PDU that was queued internally.

Steps to Replicate: This problem is not reproducible.

Platform/Feature: SBC

Portfix SBX-92580: The SIP Domain is missing in FROM header after an upgrade. (Originated in release 7.2.3).

Impact: The DM rule for the FROM URI is not working.

Root Cause: It was introduced in a previous bug fix to treat FROM URI for a specific RewriteIdentity.

Steps to Replicate: Configure PSX for the FROM URI, and on a SIP-SIP call. Verify FROM header is picking up the DM rule from the FROM URI.

Platform/Feature: SBC

The SBC introduces a static in the custom Announcement.

Impact: If the issue is not fixed, the quality of the announcement will be insufficient.

Root Cause: A software bug in the DSP was resetting the first sample of every announcement frame to zero.

Steps to Replicate:

Note: Any call flow that involves using TPAD to play announcement can work correctly.

1. The set-up requires SBC and PSX. A PSX script is implemented which has information about what announcement to play and DTMF digits that need to be entered to switch to the second stage of the call.
2. Client makes a call to SBC. In the first dip SBC plays the announcement configured in the script and waits for DTMF digits to be entered.
3. A route is present in PSX for DTMF digits entered.
4. After entering digits, PSX now goes for second dip for the new digits entered and returns a route to SBC.
5. With this route, SBC calls Egress end point.
6. Monitor the announcement quality played at step #2..

Platform/Feature: SBC

In I-SBC, PKT Port redundancy support is not present in 7.2.2 release.

Impact: SBC Release 7.2.2 is missing PKT Port redundancy support, when it is listed as available.

Root Cause: In I-SBC, PKT Port redundancy support is added in 8.x releases, but not present in the 7.2.2 release.

Steps to Replicate: Configure pkt port redundancy, do port switchover to see the service continuity on PKT ports with redundancy enabled.

Platform/Feature: SBC

Sending an a=inactive to the late media re-INVITE, after a peer put the SBC on hold, does not comply with RFC.

Impact: The SBC running 721R2 is responding with 'a=inactive' instead of 'a=sendrecv' in the 200ok SDP to late media re-invite causing no audio.

Root Cause: Requirement to send a=sendrecv in this scenario was missed.

Steps to Replicate:

Step 1: From logs, generate sipp scripts using the dbgDecode.pl utility provided by Ribbon TAC.
Step 2: Setup 7.2.1 system without fix.
Step 3: Run the call flow to see that the problem is observed.

To Verify:
Step 4: Change ScmProcess with release having the fix.
Step 5: Make call to observe that SBX is sending a=sendrecv in 200 OK.

Platform/Feature: SBC

Portfix SBX-91332: Getting the IP peer current statistics for individual IP peer was not working. The issue is reproduced when multiple IP peers are configured under same zone. (Originated in release 8.1.0).

Impact: Getting the IP peer current statistics for individual IP peer was not working.

Root Cause: The comparison of IP Peer specified in the CLI with the IP Peer statistics list was missing. Due to this issue, more than one IP Peer is configured under same zone, and the statistics for first IP Peer in the list are always used to get selected.

Steps to Replicate: Multiple IP Peers need to be configured under the same zone to reproduce this issue.

Platform/Feature: SBC

Portfix SBX-90654: A parked call was not working correctly because the NRMA process had incorrectly swapped PSP information on the call legs. (Originated in release 7.2.1).

Impact: The SBC was unable to retrieve a parked call.

Root Cause: This is a new call scenario being implemented for MS Teams interop.

Steps to Replicate: Run a test call in MS teams for call park and retrieve.

Platform/Feature: SBC: MS Teams

Portfix SBX-88122: In scenarios where MS Teams referred the call to another, the SBC started to play a RBT (ring back tone) and if the REFER failed due to the C-party not answering, the media could not be established again between the A and B party. (Originated in release 7.2.1).

Impact: Media is not re-established on A-B call when REFER to C fails.

Root Cause: The media resource used to play the RBT did not get freed up correctly when the REFER failed and this blocked the media flow from A to B being re-established.

Steps to Replicate: Make a call from PSTN to MS Teams, have MS Teams REFER the call to another user. Let the phone ring as C-party but do not answer it.

Platform/Feature: SBC: MS Teams

Portfix SBX-87861: While performing a port switch-over, observed that the SBC active went for reboot and Standby did not takeover the calls. (Originated in release 8.1.0).

Impact: The SBC does not properly put calls on Standby when a switch-over occurs.

Root Cause: A cable pull was resetting calls on the interface, which took more than 5 seconds and exceeded the health check threshold, causing the thread to lock on reset.

Steps to Replicate:

• Bring up setup in port redundancy setup.
• Cable pull packet interface to trigger port switch over.

Platform/Feature: SBC

If there is an SBC switch-over after the call is established, there can be a delay (e.g. 30 seconds) to re-establish the media from the PSTN to MS Teams direction.

Impact: The media may have a delay (e.g 30 seconds) when re-establishing.

Root Cause: The stored SSN value does not get updated before an SBC switch-over occurs, and it causes the SSN to jump backwards after a switch-over and causes the one way audio issue for sometime until the SSN value increments past the previously sent value.

Steps to Replicate: MS Teams to PSTN call flow with DLRBT enabled on a software SBC. Perform a switch-over after the LRBT is played and check there is no one way audio issue.

Platform/Feature: SBC: MS Teams

Portfix SBX-91257: The SBC was playing ring back tone while processing REFER and transferring the call. However, the tone was not heard on the original call leg because MS Teams had put the original call on hold. (Originated in release 7.2.1).

Impact: Calls on hold do not hear the ring back tone, while original calls do.

Root Cause: The code was intentionally not sending re-INVITE messages in this scenario before.

Steps to Replicate: Run any MS Teams transfer call scenario.

Platform/Feature: SBC: MS Teams

Portfix SBX-91820: The SBC was immediately disconnecting the SRS call after establishing the SIP Rec session with the next available SRS when the initial SRS has responded with a failure 4xx response. (Originated in release 7.2.1).

Impact: The SBC was disconnecting the SRS call.

Root Cause: The SBC, after finding next reachable SRS when the initial one has failed with 4xx, created a new SIP Rec Call Block data matching to new SRS. For the old SIP Rec Call Block, the state machine was invoked with a wrong event and this wrong event in the state machine was deleting the old SIP Rec Call Block along with new one.

Steps to Replicate:

1. Create a SRS Group with three SRS Servers
2. Configure num streams to 2.
3. SBC Tries to send SRS Invite to first two SRS
4. Send 4xx from the first SRS and 2xx from the Second SRS
6. After the 4xx SBC tries to send new INVITE to 3rd SRS
7. Send 2xx From 3rd SRS
8. At this step after ACK towards 3rd SRS, SBC Immediately sends BYE to third SRS

Platform/Feature: SBC

SSREQ server has memory leak, which could soon eat up virtual memory when there is call load via SSREQ client.

Impact: The SSREQserver memory will leak, when there is call load via SSREQ client.

Root Cause: The memory allocated for call data and call trace not being deleted properly, leaving those memory blocks idle forever.

Steps to Replicate:

Without the fix, memory growth can be seen every minute. Ribbon test observed 1 call per 5 second SSREQ traffic, the memory used by SSREQ grew from 0.5% to 10% in less than 30 minutes.

Platform/Feature: SBC

When the SBC sends out re-INVITE messages on a call leg supporting ICE, it can still include a=rtcp:<rtp port + 1> value in SDP that is different to the previously agreed RTP/RTCP mux setup agreed with the remote end.

Impact: MS Team scenario with ICE causes RTCP port with X when RTP is Y and when mux is supported. 

Root Cause: The SBC was not considering the SDP answer from the peer when setting the RTCP port value.

Steps to Replicate:

1. SBX routes the INVITE to egress endpoint via egress TG. INVITE should have valid SDP including -

In SDP audio stream -
RTP and RTCP ICE candidates
a=rtcp-mux
a=rtcp: which has port number of audio rtp+1

2. SBX must send 180 and 200 OK to ingress endpoint and include valid SDP for audio stream.

3. Valid ACK received.

4. SBX routes the re-INVITE to egress endpoint via egress TG. re-INVITE should have valid SDP including -
In SDP audio stream -
RTP ICE candidates (no RTCP as egress has already agreed rtcp-mux)
a=rtcp-mux
a=rtcp: which has same port number as audio rtp (as this is not initial offer for this stream and rtcp-mux has already been agreed)

In SDP video stream -
RTP and RTCP ICE candidates (as this is initial offer for the video stream)
a=rtcp-mux
a=rtcp: which has port number of video rtp+1 (as this is initial offer for the video stream)

5. Call signaling completed and then call cleared.

Platform/Feature: SBC

When a user navigates to a SIP trunk group or DM PM rule creation screen, there is no response from the UI and after some interval of time, "Proxy error" is shown to the user.

Impact: The browser is timed out, resulting in "Proxy error" to the user.

Root Cause: The EMA reads the DM PM Rule, DM PM Sub Rule and DM PM Criteria data from CDB via Netconf interface. With large amount of data, there is a significant delay in rendering the UI. Due to the request, the browser is timed out resulting in "Proxy error" to the user. Copying the TG will take approximately 3 minutes.

Steps to Replicate:

1. Configure more than 25000+ DM PM Criterias and 25000+ DM PM Rules.
2. Navigate to SiP Trunk Group Creation Screen or DM PM Rule creation screen.
3. The create screen does not load and after some time results in Proxy error.

Platform/Feature: SBC

Portfix SBX-91750: Observed a "SamProcess" core dump on an active box while running SIP-GW calls.

Impact: SBX may core if the GW Signaling Port configuration is disabled while the GW Signaling Link is up.

Root Cause: The core is caused by an attempted NULL pointer access.

Steps to Replicate: Disable the GW Signaling Port while the GW Signaling Link is up.

Platform/Feature: SBC

Multiple nodes switched over and caused outage.

Impact: Under certain conditions, the SBX sends out a duplicate OPEN_ACK, causing the receiving GW to crash.

Root Cause: Not reproducible.

Steps to Replicate: Steps are not reproducible.

Platform/Feature: SBC

The service instant messages for "Call_Hold" and "Call_Retrieve" are not generated in some GW-GW scenarios.

Impact: When SIP-SBX-GW-GW-GSX-ISUP call is intercepted, if hold/retrieve is received from either side, the SBC is not sending service instant messages to the LI server.

Root Cause: The SBC is not sending service instant messages to the LI server.

Steps to Replicate:

Setup
SIP---GW(SBX)-----GW(GSX)-------ISUP
Description:
When call HOLD comes from called (egress), GSX does not send service instance to the intercept server.

Steps to Verify:
Ensure the setup above is active.
1. Start the LI server
2. Initiate SIP-ISUP call with HOLD from egress
3. Check LI server logs for service instance msg for hold and retrieve.

Platform/Feature: SBC

Portfix SBX-87727: There was a SNMP-USER-BASED-SM-MIB Namespace Change.

Impact: The EMS cannot configure the SNMP-USER-BASED-SM-MIB through NETCONF.

Root Cause: The SNMP-USER-BASED-SM-MIB is not exposed to NETCONF.

Steps to Replicate: The steps cannot be replicated.

Platform/Feature: SBC

The BRM redundancy messages were filling up the DBG logs.

Impact: The BRM redundancy messages were filling up the DBG logs.

Root Cause: The redundancy messages were debug messages to help debug a resource leaking issue. The messages must be moved to lower level.

Steps to Replicate: The steps cannot be replicated.

Platform/Feature: SBC

The D-SBC DFE module, which controls connections to the MSBC/TSBC, continues to read memory after being freed.

Platform/Feature: SBC

The SCM Process cores when making a REFER call where more than two SCMs are present in an I-SBC configuration. When the scenario occurs, the SBC does not recognize the N:1 Slot and will not pick the changes.

Platform/Feature: SBC

The SCM may core due to memory corruption caused by processing Global PCDR Info received from the Policy Server.

Platform/Feature: SBC

During the write process to create a new policy status reporting file, the correct read privileges were not present to allow the successful completion of the status reporting session.

As a result, the status reporting process wrongly reported a sync in progress.

Platform/Feature: SBC: Application

Portfix SBX-86468: When the "Registration Expires in Expire Header" flag is enabled in the surrogate registration on Ingress TG IPSP, the de-registration is sent before the registration can refresh, which results in a call failure. (Originated in release 6.2.3F2)

Platform/Feature: SBC

The SBC added a REFER method in the Allow header when the condIncMethInAllowHdr was enabled, though REFER is set to Reject in TG methods instead of Allow Only.

Platform/Feature: SBC

PortFix SBX 72693: FPGA failures are observed on DSP cards. (Originated in release 8.0.0)

Platform/Feature: SBC: DSP

When the SBC does not find the route information when adding the Max-Forwards header for an incoming call, the SBC rejects the call.

Platform/Feature: SBC

When the PCRF is enabled, a SCM may core on switchover.

Platform/Feature: SBC

The SBC reads the end of a memory block while processing DTLS signaling. This can result in invalid accessing of memory.

Platform/Feature: SBC

The SBC CDR 'GMT' timestamps are skipping forward and backward in some call scenarios.

This issues causes call incorrect start/stop/duration timestamps in the CDRs.

Platform/Feature: SBC: CDR

Extra CR, LF (0x0d, 0x0a) characters are added at the end of an ISUP MIME body, immediately before the correct CR, LF is associated with the boundary line.

Platform/Feature: SBC: SIP

The Active SBC may fail to synchronize ("Call/Registration Data" remains in syncInProgress) after an LSWU upgrade of the Standby SBC when using an IpPeer pathCheck profile.

Platform/Feature: SBC: Application

Transport is not correctly set while the SBC is sending an Authorization request.

Platform/Feature: SBC

The code is modified to set a correct transport type while sending an Authorization request.

Impact: The SCM process may core dump.

Workaround: No workaround available.

Impact:

The RTP monitoring feature will not work for IPv6 terminated peers, and therefore the following behavior will be observed.

1. If The SBC is in tone playing state and expecting media cut through after successful monitoring, the SBC will continue the tone play even though the expected RTP packet count is received, which is discarded by the SBC because of this issue.
2. If the SBC does not have conditions for delayed tone play, is not in tone playing state and is expecting media cut through after successful monitoring, the SBC will discard media packets because of this issue.
3. If the SBC has conditions for delayed tone play, is not in tone playing state, and is expecting media cut through after successful monitoring, the SBC will discard media packets because of this issue and therefore the delayed tone play starts because of the monitoring failure.

Workaround: no workaround for IPv6, but the same feature works for IPv4.

Impact: A PDU of a size less than 6K is rejected with 400 Bad Request, when maxPduSizeValue is set to 6K.

Workaround: Increase the maxPduSizeValue to 15k.

Impact: While upgrading from pre-7.1 releases to 7.1 and 7.2 releases, if the SNMP trap targets are setup with <space> in the name field then the upgrade fails. This affects all the platforms (SBC 5xxx/7xxx/SWe).

Workaround: Prior to the upgrade, the user must check and delete/replace any trap targets that are setup with <space> in the name.

SBX-74179

1

Impact: IPv6 with X710 NIC cards in SRIOV mode will not work as multicast packets will be dropped by the PF.

Workaround:

Set the trust mode to "on" for all the VFs on the computes.

ip link set dev <PF name> VF <vf id> trust on

This needs to be done for all computes and all created VFs (this change is not persistent across reboots). This will allow Multicast promiscous mode to work.

Otherwise, add a static neighbor table entry on the remote servers connecting to the SBC using the following command:

ip -6 neigh add <IPv6 address> lladdr <link-layer address> dev <device>

SBX-73218

Platform/Feature: SBC CE: Application

Impact: Virtual ports intermittently stop responding on compute node running on RHOSP 13 (Queens) under certain conditions. Specifically, at 1000 RPS with refresh registration interval at 180 seconds, virtual ports stop responding after reaching 500K registrations. This issue is not seen when the refresh registration interval is configured as 200 seconds and above

Workaround: Use SR-IOV ports only when using RHOSP 13 (Queens) release.

SBX-73943

Platform/Feature: SBC Core: Application

Impact: The call signaling and media work properly, but media clipping can occur if the final cut-thru codec received from UAS is different from the codec that is being used for playing tone. 

Workaround: No workaround available.

SBX-74945

Impact: Commit cannot be issued in for all set commands until the ipInterfacegroup is committed.

Workaround: Commit should be issued for ipInterfacegroup first and then commit for the remaining set commands can be executed.

SBX-73660

Platform/Feature: SBC CE: Application, EMA/EMS

Workaround: Add a static route to EMS from the SBC through management interface.

Memory congestion was observed when executing around 64K calls in the 32GB SWe system.

Platform/Feature: SBC SWe: SIP-Peering

Impact: On a SWe system with 32GB 32vCPU, the SBC is only able to scale up to 60K calls instead of 64K, due to per call memory increase.

Workaround: No workaround available.

Observing 503 response for more time post port SWO in S-SBC.

Platform/Feature: SBC CE: Application

Impact: The load is 1000cps/120K calls. After doing port SWO on S-SBC, SBX rejects calls with a 503 response for 86 seconds. Later SBX again responds with 503 responses for approx 36 seconds. After that, it stabilizes.

Workaround: No workaround available.

The SBC is not able to handle 150 Sa/Sec IPsec load on the Yellowfin Platform.

Platform/Feature: SBC 5000/7000 Series: SIP

Impact: If the rate for IPsec SA setup using IKE is increased beyond 60 SA/s, errors are seen.

Workaround: No workaround available.

SBX-72652

The PSBC observing system is in continuous iRTT congestion during the overload test.

Platform/Feature: SBC CE: Application

Impact: IRTT congestion is observed continuously for the 15 mins duration of 3x overload. There is no congestion during normal 1x load. This is 1000cps/120K in DSBC (PSBC).

Workaround: No workaround available.

The SBC failed to generate Enum lookup after updating the dynamic metaVariable.

Platform/Feature: SBC CE: Application

Impact: Enum lookup fails to generate if the meta variable related to sipSigPort (used for the Enum lookup) is dynamically updated.

Example:

Before updating sipSigPort with new dynamic metaVariable:

admin@vsbc1% show global servers lwresdProfile

lwresdProfile DEFAULT {

    description          DEFAULT;

    enumDomainNameLabel  DEFAULT_ZONE_LABEL;

    enableLwresdLog      disable;

    type                 signalingIp;

    addressContext       default;

    eDnsGlobalBufferSize 4096;

    eDnsMonitorInterval  120;

    zone                 ZONE_ING_V6;

    sipSigPort           3;

    ipInterfaceGroupName LIG_ING_V6;

}

admin@vsbc1% show addressContext default zone ZONE_ING_V6 sipSigPort

sipSigPort 3 {

    ipInterfaceGroupName      LIG_ING_V6;

    portNumber                5060;

    mode                      inService;

    state                     enabled;

    transportProtocolsAllowed sip-udp,sip-tcp;

    ipVarV6                   IF2.IPV6;

}

ENUM query is not picking new sipSigport (fd00:10:6b50:5d20::c7) updated with dynamic metaVariable

Workaround: Do not update the metavvariable associated with a sipSigPort if Enum is being used.

Example:

Don't update the sipSigport to new metaVariable

admin@vsbc1% show addressContext default zone ZONE_ING_V6 sipSigPort

sipsigPort 3 {

    ipInterfaceGroupName      LIG_ING_V6;

    portNumber                5060;

    mode                      inService;

    state                     enabled;

    transportProtocolsAllowed sip-udp,sip-tcp

    ipVarV6                   IF2.IPV6;

}

Platform/Feature: SBC CE: Install/Upgrade(Platform)

Workaround: There is no workaround that is not service impacting.  Do not execute the Recreate_destroy option on a VM that has DHCP enabled.

Platform/Feature: SBC CE: Application

Impact: The old IP address is not getting deleted when the ipInterfaceGroup is updated with new dynamic meta variable.

Example:

Before updating ipInterfaceGroup with dynamic metaVariable:

admin@vsbc1> show table system metaVariable | match IF2.IPV6

vsbc1-10.34.195.109  IF2.IPV6      fd00:10:6b50:5d20::a9

Workaround: To change an addressContext ipInterfaceGroup to use a different ipVarV6 you must delete the ipInterfaceGroup and recreate it.

Example:

Delete the interface group:

 delete addressContext default ipInterfaceGroup LIG_ING_V6

Create interface group with new dynamic metaVariable:

admin@vsbc1% show addressContext default ipInterfaceGroup LIG_ING_V6

ipInterface PKT_ING_V6 {

    ceName      SSBCACTIVE;

    portName    pkt0;

    mode        inService;

 Note: Similar procedure for IPV4.

The RTCP port is not transparently passed in Direct Media.

Platform/Feature: SBC Core: Application

Impact: In case of a Direct Media call, the SBC will add an RTCP port in the outgoing INVITE SDP, when RTCP is enabled on Egress PSP and the RTCP port was not received in the incoming INVITE SDP.

Workaround: Disable RTCP flag on Egress PSP.
