SBC Core 07.02.01R000 Release Notes

V05.01.00F007

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 was 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 was 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 was 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 was modified to not delet 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 was 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.

Platform/Feature: SBC: EMA, Platform, Security

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 was 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

Commons FileUpload package file to the latest version was updated to the latest version.

SBX-85110

Platform/Feature: SBC 5000/7000 Series: Common Sonus Platform Services

SBX-74066

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 was 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: EMA, Platform, Security

Platform/Feature: SBC Core: SIP

The SBC was unable to reach the benchmarking count of 150000 on bluefin setup.

Platform/Feature: SBC Core: Performance

A New configuration flag, sipTcpConnectionAgingState, is introduced to control the Aging timer. 

If sipTcpConnectionAgingState is disabled, then TCP connections are maintained even if they are Idle for more than an hour. 

If sipTcpConnectionAgingState is enabled, then TCP connections are guarded by the Aging Timer and connections are removed if they are found Idle for more than an hour.

PortFix SBX-76978: When the SBC has /var/log mounted on the external cinder volume, /home/sftproot/evlog is missing. This causes EMS statistics collection to fail.

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

PortFix SBX-76861: AIDE service is disabled initially, but can be enabled by user. False positives are reported by AIDE.

Platform/Feature: SBC: Common Sonus Platform Services

Temporarily disable AIDE to avoid false positives. Full implementation to provide user controls will undo this change.

Platform/Feature: SBC

SBX-85187 / SBX-76066

PortFix SBX-76066: When the RTP monitoring profile is configured for a non-zero monitoring period, NP does not send any notification to the application for IPV6 RTP packets.

Platform/Feature: SBC CE: Application

SBX-76501

Platform/Feature: SBC Core: SIP Access

With the embeddedRegInfoInUserPart flag enabled, the SBC now sends the same Contact's userpart in the request/responses towards the application server which was sent earlier in the REGISTER message.

SBX-85190

The UserPart received in Request URI of INVITE was truncated in the SBC, leading to call failures. 

Platform/Feature: SBC Core: Application

Verstat parameter is sent in the egress INVITE in the PAI header when privacy transparency is enabled in PSX and 'Do not Sent Received value' for verstat param is enabled in the STI Profile.

 Platform/Feature: SBC SWe: SIP

The code was modified to give precedence to the STI profile control and allow modification to the PAI header according to that profile setting. This change in precedence allows the "verstat" parameter to be removed from the PAI header if configured within the STI profile.

NWDL License activation failed and core dumped was observed on standby node.

Platform/Feature: SBC CE: EMS

PortFix SBX-76448: The SBC core dumped if P-Com.Session-info with SIP URI of the format sip:host is received.

PortFix SBX-76497: M-SBC #3 in cluster 1 does not report in sync in the rgStatus. It is stuck in a sync state until rebooted.

Platform/Feature: SBC CE: Redundancy

Changes were made to clear node parameters for the node on which a member-failed event is received. Changes were also made to update the current role and service ID for the standby node in case member-failed is received for any other node, in order to avoid the race condition where member-failed and custom event may be received in quick succession due to a very short duration network glitch (< 1second).

After setting the new CLI aggregate policer to unlimited, the bucket size and fill rate are set to 0pkt/s and block all packets.

Platform/Feature: SBC 5000/7000 Series: Security

PortFix SBX-76500: Dead air occurs on the node after network maintenance because the same IP address is assigned to different SBCs.

Platform/Feature: SBC SWe: EMA

PortFix SBX-72973: "Do not include SS in re-Invite" IPSP flag Config on egress but affect on ingress.

Platform/Feature: SBC Core: SIP

The code was modified to check the flag based on Ingress or Egress leg.

SBX-73174

Platform/Feature: SBC Core: CLI

PortFix SBX-73149: SIP-SIP call flow works, but the SBC is still sending PEM to Ingress once it sends INVITE to Egress instead of waiting until Egress media cutthrough is done.

Platform/Feature: SBC Core: SIP

SBX-73360

CDR version for 7.2 needs to be captured in the relevant documents. CAM header fields need to be updated.

Platform/Feature: SBC Core: CDR

PortFix SBX-73040: For a SIP-GW-GW-SIP call flow, when the PSX sends a translated number to Ingress SBC1, the Egress SBC2 sends a translated number to Egress SIP endpoint. This behavior was altered starting with SBC 6.0.

Platform/Feature: SBC Core: Gw-Gw, SIP

The code was modified to ensure that the Egress SBC sends the original called number to the Egress SIP endpoint in the outgoing INVITE.

PortFix SBX-73417: A queued reINVITE, race 491 conditions, and ACK with a different branch parameter value causes call failure. 

Platform/Feature: SBC Core: SIP

Platform/Feature: SBC Core: SIP

PortFixSBX-74073: The SBC gives a response error when itrecievesa generic parameter with IPv6reference value.

Platform/Feature: SBC Core: SIP

PortFix SBX-74234: During split brain recovery, the becoming-standby SBC may send packets out of pkt interfaces after GARPs are sent by the active SBC.

Platform/Feature: SBC 5000/7000 Series: HA

PortFix SBX-73913: Split brain recovery may lead to blacklisted IP peers. In a split-brain scenario when the SBC application is brought down, the cleanup script invoked toggles the pkt ports. When the pkt port goes up, ICMPV6 packets are sent out to the pkt ports. The switch may map the wrong port with the active MAC address and start sending packets to the standby SBC. The packets should not be sent.

Platform/Feature: SBC Core: Application, Platform

PortFix SBX-69137: During IMS-AKA registration, IPSec policy and SA are configured in kernel and during de-registration, they are removed from kernel.

An issue in kernel IPSec code causes memory allocated for IPSec policy to not be freed even though IPSec policy was removed from kernel by application. This causes a memory leak in kernel module for each registration and the memory leak gradually increases as the number of registrations increases. 

Platform/Feature: SBC SWe: IPSec, SIP

PortFix SBX-74127: MemUsage logs are not displayed in EMA.

Platform/Feature: SBC 5000/7000 Series: EMA

The code was modified to add support for Memory Logs.

PortFix SBX-72774:  SBC was not able to convert when a state where ICE learning was completed to a state where ICE was not required on the call flow due to call forking. This lead to no audio after the call was set up. 

Platform/Feature: SBC Core: SIP

PortFix SBX-74387: E2E reINVITE caused the application offer to timeout. If a new offer is the same as a previous SDP, SIPS fails to send out a reINVITE.

Platform/Feature: SBC Core: SIP

PortFix SBX-73433: Call failures occur due to Lif with no available ports.

Platform/Feature: SBC 7000 Series: Platform IP/Media Services

Platform/Feature: SBC 5000/7000 Series: SIP

The code was modified to prevent copying from unmapped memory.

PortFix SBX-73636: The SBC did not auto-recover after double failure.

In a case where both active and standby SBC processes go down in succession, it can lead to a state where active SBC node may continue to run as standby even if there is no node running in active mode in the redundancy group.

Platform/Feature: SBC CE: Platform

Platform/Feature: SBC Core: Application

PortFix SBX-74514: The SBC (which later becomes standby) sends GARPs after GARPs are sent by the SBC (which stays active) after split brain recovery.

Platform/Feature: SBC 5000/7000 Series: SIP, TLS

The SBC EMA does not allow uploading token files with the file upload as the token file extension is not supported in the file upload.

Platform/Feature: SBC Core: EMA

The code was modified to allow token files to upload successfully and to load the values from the token file into the Configuration script form.

PortFix SBX-74051: Under a heavy load, while using IPSec AKA TCP feature, the SAM process may coredump due to the code not handling an error condition correctly.

Platform/Feature: SBC SWe: IPSec, SIP

PortFix SBX-67713: When sendRouteUriToPsx is enabled, useRouteSet is set as received, and the SBC receives NOTIFY before 200OK for SUBSCRIBE is received, the SBC sends NOTIFY received from the core side back to the core side instead of relaying it to the access side. 

Platform/Feature: SBC Core: SIP

The M-SBC cannot establish IPSec connections after reboot/respawn during LSWU initiated switchover due to a pre-shared key getting re-encrypted. Encryption keys are not installed to the upgraded instances, due to which the instances are not able to decrypt the pre-shared key.

Platform/Feature: SBC CE: Application

PortFixSBX-72547: GW-GW call fails when a LM Re-INVITE is received with passthrough configuration as the PAM message is not sent to egress gateway.

Platform/Feature: SBC 5000/7000 Series: SIP

The code was modified so that GW-GW calls do not fail. GW1 now sends MCS PAM to GW2 on receiving a Re-INVITE without SDP.

PortFix SBX-75463: After TG delete, the SBC accesses an invalid TG address, causing SCM to coredump.

Platform/Feature: SBC Core: SIP Applications

PortFix SBX-75052: After a switchover, SBC will randomly pick a media IP address on sipTrunkGroups that has mediaIpAddress configured. 

Platform/Feature: SBC SWe: SIP

Platform/Feature: SBC Core: SIP

PortFix SBX-64175: In SIP call forking, there is dead air after 200 OK.

Platform/Feature: SBC 5000/7000 Series: Media Resource Management, Platform IP/Media Service

PortFixSBX-72945: Short Spikes in CPU Utilization of Management Processes triggers resource DRM Congestion Level 3 Alarms.

Platform/Feature: SBC SWe: Platform

PortFix SBX-75073: SIP Recording of a call using SRTP to a SIP Recording Server (SRS) does not work. The SBC generates malformed SRTP packets which do not reach the SRS.

Platform/Feature: SBC SWe, CE: SIP

PortFix SBX-59422: PassThrough call converted to DM after HOLD/UNHOLD resulting in packets getting discarded after unhold.

Platform/Feature: SBC Core: SIP

The SBC EMA does not allow uploading Tokens file with the Fileupload.

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.

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

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;

    eDnsMonitorInterval  120;

    zone                 ZONE_ING_V6;

    sipSigPort           3;

    ipInterfaceGroupName LIG_ING_V6;

}

admin@vsbc1% show addressContext default zone ZONE_ING_V6 sipSigPort

sipSigPort 3 {

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;

    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

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 {

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.
