SBC Core 07.02.01R004 Release Notes

V05.01.00F007

SBX-91726 / SBX-87861

PortFix SBX-87861: The SWe_NP thread hang was observed on a packet port pull out. (Originated in Release 8.1.0).

Platform/Feature: SBC

The thread health check mechanism is fixed on the port reset.

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.

Platform/Feature: SBC

Portfix SBX-91493: On a CLI port switch over, a packet interface with random connectivity loss is observed for few seconds on other interfaces. (Originated in Release 8.1.0).

Platform/Feature: SBC

In scenarios where MS Teams referred the call to another user, the SBC started to play an RBT (ring back tone) and if the REFER failed due to the C-party not answering, the media is not established again between the A and B party.

Platform/Feature: SBC: MS Teams

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

Platform/Feature: SBC: MS Teams

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

Platform/Feature: SBC

PortFix SBX-90308: When the LRBT is enabled for an ICE call, the egress endpoint responds to initial INVITE with a 183 progress message with SDP parameters followed by a 180 without an SDP and a 200 OK with SDP. Following the local ring back tone, the SBC instigates a re-INVITE to the egress endpoint, which is missing ICE ufrag, password and RTCP candidate line in the SDP. (Originated in Release 7.2.2).

Platform/Feature: SBC: SIP, MS Teams

SBX-91098 / SBX-90673

PortFix SBX-90673: When multiple users registered from the same source IP and if the SBC receives SUBSCRIBE from second user, incorrectly fetches the RCB of first user (The pilot number) and forwards the SIP pdu to the wrong SIPSG slot. The SIPSG is not able to locate the RCB and rejects the SIP message with an 403 error response. (Originated in Release 6.2.5)

Platform/Feature: SBC

SIPFE uses the user name or pilot number (pilot number selected based on user name) while fetching the RCB. If the RCB is found at the SIPFE level, then it forwards the SIP pdu to the correct SIPSG slot.

The NRS task failed healthcheck when there was over 3000 status requests per minute.

Platform/Feature: SBC

When an SRS does not respond to the SBC's request, and if no redundant SRS is configured, the SBC sends a BYE response towards an SRS without XML. Also, the SBC terminates all the SIPREC calls towards the SRS by sending BYE responses.

Platform/Feature: SBC

The code is modified to invoke the API responsible for building XML body.

The code is modified so that when there is no response from SRS for the Re-Invite, the SBC terminates only the specific SIPREC call that did not receive the response.

SBX-91386 / SBX-88070

Portfix SBX-88070: If a call to the sonusPeerUpload.expect is made and the peer goes down, the user may get stuck waiting for the scp connection, resulting in the application healthcheck timing out after 10 seconds. The timeout causes the application to crash. (Originated in Release 7.2.2)

Platform/Feature: SBC

A timeout for the scp is used in sonusPeerUpload.expect script to ensure that a user does not wait longer than 2 seconds for the scp connection to establish.

SRTP enabled calls in the SWe SBC, causing sporadic NP worker crashes.

Platform/Feature: SBC

The audio becomes one way after there is a call transfer on the SWe when Ring Back is enabled with SRTP towards a MS TEAM. The enabled Ringback with SRTP relays the one way call transfer back to the PSTN behind the SBC. 

Platform/Feature: SBC

Portfix SBX-89877: If the server sends multiple notifications without a record-route before the subscribe is stable, the SBC may core because the free memory being duplicated. (Originated in Release 7.2.2)

Platform/Feature: SBC

Unable to upload a configuration in the SBC Provision Management.

Platform/Feature: SBC: EMA/EMS

Portfix SBX-86427: When large SIP PDU's(4096 B) are sent towards a monitoring server, the SBC cores because of buffer overflow. (Originated in Release 7.2.2)

Platform/Feature: SBC

In the Configuration Script and Template Import page, when you select 'Create Configuration from Template', you choose a Configuration from the table, and select Next. This template form is not getting displayed due to some failure.

Platform/Feature: SBC

SBX-91257 / SBX-90664

Portfix SBX-90664: 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 7.2.1R2)

Platform/Feature: SBC/MS Teams

The SBC was unable to retrieve a parked call. The call did not working correctly due to the NRMA process incorrectly swapping PSP information on the call legs. (Originated in Release 7.2.1R2)

Platform/Feature: SBC/MS Teams: SIP

Scm Process cores on receiving notifications from PCRF, which Registration Control Block does not exists. (Originated in Release 5.1.5R0)

Platform/Feature: SBC

NRS task failed healthcheck when there was over 3000 status requests per minute.(Originated in Release 7.2.1R2) 

Platform/Feature: SBC: Application, confd

Portfix SBX-90061: When the SIP trunk group->signaling->s8hrSupport flag is enabled, the SBC requests the PCRF for PLMN ID and waits for response. On getting PLMN ID response (or timeout), the SBC continues the call processing but did not free up all the internal resources causing a memory leak. (Originated in Release 7.2.1R0) 

Platform/Feature: SBC

Portfix SBX-90085: When special character inputs are used for called number filter in the CDR viewer table, the input validation fails and the page keeps showing the table as 'Loading...'. (Originated in Release 6.2.0R0) 

Platform/Feature: SBC

Portfix SBX-90088: NOTIFY is rejected with 489 Bad Event after a double switchover. (Originated in Release 7.2.0R0)

Platform/Feature: SBC

Portfix SBX-88996: The single character search is an exhaustive search operation and the browser witnesses Timeout Exception and renders a the blank screen to the user. (Originated in Release 6.2.4R0)

Platform/Feature: SBC: EMA

Portfix SBX-87984: Web server leaks a private IP address through its HTTP headers. The leak will expose internal IP addresses that are usually hidden or masked behind a Network Address Translation (NAT) Firewall or proxy server. (Originated in Release 6.2.2R0)

Platform/Feature: SBC: EMA, Security

All filters do not display for the tables like Call Detail Status, Call Media Status, Call Resource Detail Status, etc. (Originated in Release 7.2.0R1)

Platform/Feature: SBC

When using EMA and accessing the Call Trace/Logs/Monitors > Log Management > TShark, the screen does not list the files if there are more than 130 files in the directory. (Originated in Release 7.2.0R0)

Platform/Feature: SBC

Portfix SBX-89586: Token load option is not loading values into a template. No action is triggered even after a user clicks on Token load. (Originated in Release 8.0.0R0)

Platform/Feature: SBC

SBX-88882

200 OK of INVITE received immediately after UPDATE/200 OK gets stuck and the call fails. 

Platform/Feature: SBC

SBX-88326

PRACK for locally generated 18x is relayed to other leg. This is because of bNw18xRcvd flag not reset when CallProgressCmd is called.

Platform/Feature: SBC

SBX-87795 / SBX-87053

PortFix SBX-87053 (Originated in Release 8.0.0): Failed to apply ARS procedure on getting 503 (when FQDN and uriPreference configured on Egress side).

Platform/Feature: SBC

SBX-89651 / SBX-87342

PortFix SBX-87342: SIP 503 error occasionally occurs in a test.

The issue is seen because the SBC wrongly identified INVITE PDU type as OTHER and not INVITE only in the case when the first partial PDU is received over TCP as a fractional INVITE word.

Platform/Feature: SBC

SBX-89333 / SBX-87140

PortFix SBX-87140 (Originated in Release 7.2.2): First, DNS query was getting initiated through management even if IP was configured.  As default static routes are configured and management gets the preference, the DNS query was initiated through the management interface. 

Secondly, the Patchcheck process core dumped when a truncated DNS response was received from DNS server. The Patchcheck process core dump was happening because of its inability to handle a truncated DNS response. 

Platform/Feature: SBC

SBX-89383 / SBX-86553

PortFix SBX-86553 (Originated in Release 7.2.2): The SBC is not responding for ping request of higher bytes of 2000 using x710 NIC's.

SBX-89383: IP Fragmented Packets on X710 NIC will have issues and will get dropped. Due to this large packets with or without VLAN will be dropped and not handled by the SBC.

Platform/Feature: SBC

SBX-89110

The SCM deadlock core dumps.

Platform/Feature: SBC: Application

SBX-89567

Platform/Feature: SBC

BMC Serial Port skips character of input data, causing command failure.

Platform/Feature: SBC: BMC

When a high number of endpoints are registering and un-registering frequently, the ScmProcess core dumps while deleting the registration control block for registration where the SIP redirecting server sent multiple contacts in a SIP 3xx response.

The SBC system starts and stops a very high number of timers for call and registration functionality to work correctly and assigns a timer ID as an incremented integer value. When the number of timers the SBC has started since startup is more than 4 billion (unsigned int32 bit max value), the next timer ID the SBC assigns is a wrapped value of 1. At this time, if there are any timers in use using a low timer ID, the SBC will fail to start the timer. If the start timer fails for a registration with the redirecting server sending multiple contacts to the SBC, the ScmProcess may core dump while deleting the registration control block.

Platform/Feature: SBC Core: Platform

The Scm Process core dumps while trying to double free the memory associated with the username of registration of the AOR.

The previous register AOR block was freed. However, the username field was not set to NULL and a subsequent re-registration or refresh reuses the heap memory that was freed for the previous registration. When trying to free the current registration block, double free is detected and core dump occurs.

Platform/Feature: SBC

SBX-88482/SBX-87601/SBX-88477/SBX-85988

PortFix SBX-87601: The SBC is dropping the userpart in the RURI of the outgoing INVITE.

Platform/Feature: SBC

PortFix SBX-88254 (Originated in Release 6.2.3F3): The SBC rejects SUBSCRIBE requests with 403.

Platform/Feature: SBC

PortFix SBX-87944: A blind transfer call occurs due to DLRBT. The internal tone flag on leg B was not reset properly. As a result, leg C fails to cancel the tone. 

Platform/Feature: SBC

PortFix SBX-86593 (Originated in Release 6.2.4): The EMA Template fails to import the configuration when Special Characters are present.

Platform/Feature: SBC

A memory leak occurs when rewriteIdentities is enabled on a SIP trunk group. If a SIP trunk group has rewriteIdentities enabled, there is a case in which memory that was allocated for temporary storage of a toHeader is never freed.

Platform/Feature: SBC

SBX-86783 / SBX-73424

Platform/Feature: SBC: CDR

SBX-86608

Platform/Feature: SBC

Wrt key-salt generation validation is added.

SBX-86790 / SBX-86589

PortFix SBX-86589 (Originated in Release 7.2.2R0): Sip sig port is not responding to ARP if the ARP request comes on an interface which the sip sig port is not bound to.

Platform/Feature: SBC Core: Platform IP/Media Services

SBX-85675

Random Java code writing from Rest interface as the json dependency was not loaded.

Platform/Feature: SBC

SBX-86735 / SBX-86694

PortFix SBX-86694 (Originated in Release 8.0.0R0): Transfer cases failing as E2E PRACK needs to be disabled on transfer Leg, as provisional responses will not be relayed to other leg.

Platform/Feature: SBC

SBX-85676

Reading any file from un-privilege Rest User from REST GET Request is not validated as the curl command was not sanitized.

Platform/Feature: SBC

SBX-85742

Support for In dialogue REFER request when Response is present.

Platform/Feature: SBC

The code is modified in the SIP stack. If the Message type is REFER and PSX Response profile is configured before a response is sent to network, add the Custom Reason Text from the PSX Response Profile and not the default one.

If in the IPSP "Include Reason Header" is enabled, the SBC will Add Q.850 Reason header with the cause code, Reason text of Q.850 Reason Header configured into Response Profile.

When the SBC does not find the route information for incoming call, it rejects it with Error response. In the error response message, Max-Forwards header was being added. 

Platform/Feature: SBC

Issue 1: A 488 was sent because of Nrma Modify Failure when UPDATE followed by 18x without SDP was received. This is caused by Prack pending.

Issue 2: A 491 is issued when UPDATE is received immediately after 18x without SDP. This is again caused by Prack pending.

Platform/Feature: SBC

Issue 1: Added a flag check and OfferAnswer check to avoid this issue.

Issue 2: Added a flag check to avoid this issue.

REFER Relay is not working in S-SBC.

The SBC allows REFER to be Relayed to the egress side in a D-SBC environment. It would reject REFER that should be acted upon if REFER Relay is not enabled.

Platform/Feature: SBC

The SBC does not handle IP fragment timeout properly. When IP fragment timeout occurs, the fragment context is deleted and the per-nif in use count is decremented. There is a problem in the code where it decrements the incorrect nif.

The SBC's ability to handle de-fragmented packets will deteriorate. The NO DEFRAG MATCH count in "show table system networkProcessorStatistics defragStatistics" increments rapidly. If PSX responses are large and the IP packets are fragmented, you may see the SBC retry multiple times due to reassembly failures resulting in packet drops. 

Platform/Feature: SBC

When pcrf is enabled, SCM may core on switchover. 

Platform/Feature: SBC

PortFix SBX-68858: The SBC CDR 'GMT' timestamps jumped forward and backward.

Platform/Feature: SBC: CDR

PortFix SBX-86992 (Originated in Release 6.2.4R0): SCM may core due to memory corruption caused by processing of Global PCDR Info received from Policy Server.

Platform/Feature: SBC

While triggering a recording call towards SRS for a SIPREC Redundancy scenario, the SBC fails to build the XML Metadata Information which failed to trigger the Recording call.

Platform/Feature: SBC

PortFix SBX-63571 (Originated in Release 5.1.6R0): The Active CE may fail to synchronize ("Call/Registration Data" stays in syncInProgress) after LSWU upgrade of Standby CE, when ipPeer pathCheck is used. The RTM process was not able to handle pathCheck messages that may occur during LSWU.

Platform/Feature: SBC: Application

CallFlow is captured properly but the sequence of the packet is out of order.

Platform/Feature: SBC

Non-default addressContext ACLs are not working.

Platform/Feature: SBC

Log packets before and after SMM translations.

Platform/Feature: SBC

NRMA fails to select the AMR codec when restricted mode set is present in Offer and Route PSP during tone play.

Platform/Feature: SBC

The SBC is not printing ingress details in callDetailStatus/callMediaStatus after switchover for REFER flow.

Platform/Feature: SBC

The SBC is not intercepting media packets of one stream post REFER.

Platform/Feature: SBC

This issue occurred as routers respond to the ARP probe request sent by the SBC with a GARP request, and the target MAC in that ARP request is set to a broadcast MAC. The SBC expects the target MAC in the ARP response sent by router to contain the MAC address of the SBC port from which the request was sent. The SBC was not treating this as a valid response, which resulted in reporting standby links as DOWN.

Platform/Feature: SBC

The SBC is not able to send local ACK after REFER when E2E ACK is enabled.

Platform/Feature: SBC

E2E ACK functionality should not kick in after call is transferred as 200 OK response does not need to be relayed to other leg. Code changes are made.

XRM deadlock. Standby keeps restarting.

Platform/Feature: SBC

The issue is fixed by the XRM inserting the xres into the encryption hashtable after state becomes active, and by processing the modify (deactive-reactive) scenario, the hash entry in map should be updated, otherwise it causes the duplicate issue.

The SBC does not honor the expires value from the registrar.

Platform/Feature: SBC

SBX-75934

PortFix SBX-76121: The SBC core dumps if P-Com.Session-info with SIP URI of the format sip:host is received. 

Platform/Feature: SBC CE: SIP

SBX-76571 / SBX-74056

PortFix SBX-74056: Call scenario is inconsistent in the case of a SIP-I/SIP call with Hold on 180.

Platform/Feature: SBC 5000/7000 Series: SIP

Validation code is added to ensure that the SBC does not send out a generic notification with hold in the backward direction until after the call is answered. It is only sent out in the forward direction after the call has routed. Retrieve is also not sent out unless hold has previously been sent out.

SBX-76013 / SBX-75378

PortFix SBX-75378: Code to free a structure is missing from camRecordDestroyOptionalFields. 

Platform/Feature: SBC 5000 Series: Call Control

SBX-76041 / SBX-74899

PortFix SBX-74899: The SBC disconnects calls intermittently. After that, the UAC sends Re-INVITE without any change in SDP, so the SBC responds locally.

Platform/Feature: SBC Core: Application

SBX-76017 / SBX-75618

PortFix SBX-75618: SIPFE found the wrong Reg AOR and route Options to the wrong SG (slot).

Platform/Feature: SBC Core: SIP Access

SBX-76052 / SBX-74160

Platform/Feature: SBC 5000/7000 Series: DSP

SBX-76016 / SBX-75864

The code is modified so that memory is properly freed.

SBX-76012

Platform/Feature: SBC Core: Application

SBX-76062 / SBX-75057

PortFix SBX-75057: SMM Dialog Statefull Variables with Dialog Transparency is not working. 200 OK for Re-INVITE sent, Bye Received and 200 OK is re-transmitted.

Platform/Feature: SBC Core: SIP

SBX-76494 / SBX-76310

PortFix SBX-76310: In downstream forking and 18x without PRACK, the SBC does not relay a 180 response.

Platform/Feature: SBC Core: SIP

The code is modified so that the 180 response is not dropped.

SBX-76492 / SBX-76059

PortFix SBX-76059: NTP security improvements needed.

Platform/Feature: SBC 5000/7000 Series: Security

SBX-72863

TPAD crashed when it was setup for internal (IDP) format but received a mix of RTP and IDP packets. This caused TPAD to delete the buffer pool, and inconsistency resulted in illegal memory access resulting in a crash. 

Platform/Feature: SBC 5000/7000 Series: DSP

The code is modified to not delete the buffer pool because IDP channel is expected to receive only fixed size IDP packets. If it receives RTP packets, it will drop RTP packets but not re-carve buffer pool. 

SBX-76453 / SBX-75458

PortFix SBX-75458: When 180 Ringing is received before completion of UPDATE-200OK during an egress precondition inter-working scenario, an issue is seen.

Platform/Feature: SBC 5000/7000 Series: SIP

SBX-76456

PortFix SBX-76182: Issues occur after SBC7K receives 181 on Egress.

Platform/Feature: SBC 5000/7000 Series: SIP

The Preconditions Update needs to be sent for 18x with SDP, and Ignore 18x needs to be sent without SDP.

SBX-75249

The error "Unable to login to peer shell, IP: 169.254.88.1" was observed after LSWU.

Platform/Feature: SBC SWe: Application

SBX-76097

The new MAC address in the received Gratuitous ARP sent by the next-hop router will update the media packet headers of the existing calls.

The previous SBC behavior was to use the new MAC address from Gratuitous ARP (G-ARP) only if the IP address in G-ARP belonged to the peer. If the peers are reachable via the next-hop router, the existing calls can experience one-way audio when the next hop router’s MAC address changes.

Platform/Feature: SBC Core: Common Sonus Platform Services, Platform IP/Media Services

The code is modified to include processing G-ARP from the next-hop router when the media peers of existing calls are reachable via the next-hop router.

SBX-76851 / SBX-62682

PortFix SBX-62682: Deleting the IP interface while in dryUp action does not work correctly.

Platform/Feature: SBC 5000/7000 Series: CLI, EMA

SBX-76844 / SBX-74460 

PortFix SBX-74460: The SBC releases ACK based on Stack State, while unaware of delayed ACK and Faking from Stack.

Platform/Feature: SBC 5000/7000 Series: Application

SBX-76857 / SBX-76611

PortFix SBX-76611: Standby Subscribe with registration accessed an invalid address, causing a core dump.

Platform/Feature: SBC Core: SIP Applications

SBX-76856 / SBX-74725

PortFix SBX-74725: "Minimize relaying of media changes from other Call Leg All" is suppressing Re-INVITE to pass through codec in REFER scenario.

Platform/Feature: SBC Core: SIP

SBX-76794 / SBX-76119

PortFix SBX-76119: For a SIP to SIP call using GW protocol between 2 SBCs with "Include OTG" selected, the OTG parameter in Egress Invite will contain GW trunk name instead of name of ingress SIP trunk group from ingress GW. 

Platform/Feature: SBC Core: Gw-Gw

SBX-76845 / SBX-71646

PortFix SBX-71646: While sending input data for certificate content, content is encoded and not read by netconf properly.

Platform/Feature: SBC Core: EMA

SBX-76876 / SBX-74280

PortFix SBX-74280: After a user logs out of EMA, some of the http sessions are not cleared, which results in stale http sessions in the heap, causing an out of memory error. 

Platform/Feature: SBC 5000/7000 Series: EMA

SBX-76971 / SBX-75802

PortFix SBX-75802: A Radius account timeout occurs.

Platform/Feature: SBC SWe: Application

PortFix SBX-75086: SCM core dumped due to an attempt to de-reference a NULL pointer. 

Platform/Feature: SBC 5000/7000 Series: Application

SBX-76972 / SBX-67707

PortFix SBX-67707: A swagger interface was exposed.

SBX-77014

Servers1 is not created in memusage log during upgrade from 5.1 to 7.1.

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

The SBC adds duplicate Via headers.

Platform/Feature: SBC Core: SIP Applications

PortFix SBX-74608: When the minimize flag is off, and after egress resume on a call on hold takes place, the SBC sends an unnecessary INVITE.

Platform/Feature: SBC Core: SIP

The code is modified to suppress re-INVITE while the call is on hold.

PortFix SBX-74611: When multiple switch over occurs, includeQ850Reason and unrecAction flags configured on custom cpcToSipCauseMapProfile are not honored and instead default values from baseProfile is used. Consequently, mapping between CPC to SIP cause code is incorrect. 

Platform/Feature: SBC Core: SIP

The platformManager has broken logic.

Platform/Feature: SBC Core: ConnexIP OS, Platform

Platform/Feature: SBC 5000/7000 Series: SIP Applications

PortFix SBX-75076: If the SBC is re-ISOed and then loadConfig is performed, it results in the loss of confd.conf encryption keys. The encrypted fields in CDB then become non-decryptable. If an upgrade is performed in such a scenario from 4xx/5xx to 7.2.x, then it will fail as confd will fail to decrypt the mandatory encrypted fields and so the fields will remain blank in CDB. During startup post upgrade, confd will exit during validation phase as it will find blank for mandatory field.

Platform/Feature: SBC Core: Install/Upgrade(Platform), IPSec

To prevent upgrade failure, upgrade code is introduced, which fills in a dummy value if an empty value fund for mandatory encrypted fields.

SBX-85446

Apache Commons FileUpload package requires security upgrade.

Platform/Feature: SBC Core: Media

SBX-76915 / SBX-66015

PortFix SBX-66015: G.711 playout buffer sizes were increased in release 6.0 as part of SBX-57507 so that the initial playout delay and jitter minimum occupancy threshold could be set at values up to 200 ms. However, the TPAD playout buffer was not increased in size, so this large setting of initial playout delay can result in a core dump.

Platform/Feature: SBC Core: DSP

An issue occurs when DB backup was restored when backup was taken from the unsupported version.

Platform/Feature: SBC: Common Sonus Platform Services

PortFix SBX-85312:  After call transfer, the media loss detection feature turned OFF as the logic hit the MGSG feature, which accidentally turned the feature OFF.

Platform/Feature: SBC: Media

The code is modified so that if not MGSG, then the feature does not turn OFF.

When HTP all header transparency is set with ignoring some headers related to Privacy, though IPSP Privacy transparency is disabled, we still send those ignored headers transparently. 

Platform/Feature: SBC: SIP, SIP Access

When sipHeader all transparency is enabled in HTP, and Privacy related headers transparency needs to be ignored, then all following headers should be ignored in HTP.

Refer to SBC SIP Transparency Implementation Guide for more information.

PortFix SBX-67707: Swagger interface exposed.

Platform/Feature: SBC Core: EMA

The Cloud I-SBC does not come up with Multiqueue enabled on RHEL 7.5.

Platform/Feature: SBC CE: Application

Multi-queue virtio instances support on OpenStack requires below command to be executed on the compute node:

1. audit2allow -a -M attach_queue. 
2. semodule -i attach_queue.pp 
3. Try spawning SWe instance again.

Impact: Interception of calls fail during upgrade (for instance, when the setup has S-SBC and the M-SBC running on different versions). The impact is only for in-service upgrade. No impact with respect to calls, when the VNF is brought down and re-created for upgrade.

Workaround: No workaround available.

Impact: In the rare case where a PRACK for 18x is dropped and the call eventually fails, a small leak of SCM memory can occur.

Workaround: No workaround available.

When a headend cluster configuration is pushed, the Standby SBC reboots and hangs without getting the Configuration.

When a Standby SBC is rebooted, it transitions to registered online then later unregistered offline. This also happens in #1, Standby reboot after Configuration is pushed.

Platform/Feature: SBC Core: EMA

Impact: When a headend cluster configuration is pushed, Standby SBC fails to download the configuration and so fails to come up properly.

Workaround: To resolve the above issue, the fill rate and bucket size needs to be increased in lca.py script and the Standby SBC system needs to be rebooted so that it can download the configuration again.

CallMedia and CallDetailstatus do not show in the EMA during the load run.

Platform/Feature: SBC Core: EMA

Impact: Call details Status and Call Media Status are intermittently not visible in the EMA.

Workaround: Call details status and Call Media status can be viewed from CLI.

Egress peer sends back two UPDATES messages during call setup. The second UPDATE is rejected with a 488. During the processing of the second UPDATE a 183 without SDP is also sent and forwarded to the ingress with 100rel.

Platform/Feature: SBC Core: Application

Impact 1: 488 because of Nrma Modify Failure when UPDATTE followed by 18x w/o SDP received. This is because of PRACK is pending.

Impact 2: 491 is issued when Update is received immediately after 18x without SDP with E2E Prack. This is again because of PRACK pending.

Workaround 1: Enable E2E Update so that update will be queued when PRACK is pending.

Workaround 2: No workaround available.

Impact: Under load with 30,000 simultaneous NP tones playing M-SBC switches over. M-SBC system confirmed to perform fine up to 28,000 simultaneous NP tones.

Workaround: No workaround available.

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.

An LSWU Upgrade from 7.0 to 7.1 failed.

Platform/Feature: SBC 5000/7000 Series: Application

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-86003

Impact: The peer may reject the call.

Workaround: No workaround available.

Issue 1: 488 occurs because of Nrma Modify Failure when UPDATE followed by 18x w/o SDP received. This is because we try to fake when Prack is pending.

Issue 2: A 491 issue occurs when UPDATE is received immediately after 18x w/o SDP with E2E Prack. This is again because of prack pending.

Platform/Feature: SBC Core: Application

Impact: UPDATES are rejected.

Workaround:

For issue 1: Enable E2E Update so that update will be queued when Prack is pending.

For issue 2: No workaround available.

Impact: A call onhold/offhold before being connected by Update may fail.

Workaround: Enable E2E Update.

A race condition occurs under a 3x load scenario where MRF is configured as FQDN and none of the MRF server responds.

Platform/Feature: SBC: DSBC

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.

An LSWU Upgrade from 7.0 to 7.1 failed.

Platform/Feature: SBC 5000/7000 Series: Application

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

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

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 

admin@vsbc1% show addressContext default ipInterfaceGroup LIG_ING_V6

ipInterface PKT_ING_V6 {

    ceName      SSBCACTIVE;

    portName    pkt0;

    mode        inService;

    state       enabled;

    ipVarV6     IF2.IPV6;

    prefixVarV6 IF2.PrefixV6;

    vlanTagVar  IF2.VlanId;

After updating ipInterfaceGroup with dynamic metaVariable (lpl) old IP (IF2.IPV6) is not deleted from interface

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;

    state       enabled;

    ipVarV6     lpl;

    prefixVarV6 IF2.PrefixV6;

    vlanTagVar  IF2.VlanId;

}

 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 is not received in the incoming INVITE SDP.

Workaround: Disable RTCP flag on Egress PSP.
