About SBC Core

The SBC Core platforms address the next-generation needs of SIP communications by delivering media transcoding, robust security and advanced call routing in a high-performance, 2RU, and 5RU form-factor devices enabling service providers and enterprises to quickly and securely enhance their network by implementing services like SIP trunking, secure Unified Communications and Voice over IP (VoIP).

For more product information, refer to the section About SBC Core in the main documentation space.

Interoperability

The SBC Core software interoperates with the following:

  • SIP/H.323 compliant IADs and IP-PBXs
  • PSX Policy Server Softswitch via SIP redirects and/or Diameter+ protocol
  • SBC 9000 through SIP call signaling and Networks MCS protocol
  • NetScore collection, analysis, monitoring, and reporting of selected Key Performance Indicators (KPIs) on a near-real time basis

Note

NetScore maintains a list of remote host keys for all nodes from which it collects data. If NetScore is deployed in your network, connectivity to the SBC will be lost any time the SBC software is reinstalled because the SBC’s host key is updated during the install. Refer to NetScore Release Notes for steps needed to reconnect to the SBC.

H.323-SIP and SIP-H323 Calls

When using H.323-SIP and SIP-H.323 call flows, an additional Re-invite/Update may get generated towards the SIP side. To suppress this, enable the IP Signaling Profile (IPSP) flag Minimize Relaying Of Media Changes From Other Call Leg at the SIP side.

Note

H.323 is not supported on SBC SWe cloud deployments.

Note

Execute the Method Of Procedure (MOP) only for upgrading the FPGA image of an SBC 7000 DSP-LC card when the SBC 7000 DSP-LC FPGA version is 0x14. The MOP can be applied at any version time, with the only restriction being that the BMC firmware version is at least 1.25.0. However, if the SBC application is running version V05.01.00R000 or higher, then the DSPs will be set to disabled and transcoding and transrating calls will fail if the SBC 7000 DSP-LC FPGA version is 0x14. Therefore, it is necessary to upgrade the SBC 7000 DSP-LC FPGA if the version is 0x14, before upgrading the SBC to 5.1.0. However, the MOP can be applied if the application version is higher than 5.1.0. Click Here to view the 550-06210_DSP-LC_FPGA_Upgrade_MOP.

Upgrade Notes

Warning

A LSWU on an SBC 7000 should only be performed when the total number of active calls on the system is below 18,000. If the criteria is not met, a double failure during the upgrade may occur thereby losing all active calls. If such a failure occurs, both active and standby SBC services will go down.  Contact Ribbon Support immediately.

Note

Release 7.2 requires additional user account security practices for SBC SWe deployments in Openstack cloud environments. During upgrade of SBC SWe cloud instances deployed using Heat templates, you must use a template that include SSH keys or passwords for the admin and linuxadmin accounts. The example Heat templates have been updated to include information on how to specify this type of data in the userdata section of a template.

Note

Once the installation or upgrade completes on the SBC 51x0 and SBC SWe platforms, the copy of the installation package (311076794) is automatically removed from the system.

Note

As an SBC Core password security enhancement, user passwords automatically expire after upgrading to 7.2.x. As a result, users are required to change their passwords upon initial login immediately following the upgrade.

Note

Customers using the Network licensing mode will stay on the Network licensing mode after upgrade to the SBC 7.2.0 Release

Customers using Legacy mode will stay on the Legacy mode after upgrade to SBC 7.2.0 Release. Once upgraded to SBC 7.2.0 Release, the customer will not be able to set Network License mode.

Note

The AWS version is currently available on an R7.0 branch. Customers should use the R7.0 branch or contact their local sales representative if they have a use case for AWS.

Note

The SBC 7.2 5xx0 and 7000 platforms may exhibit a 7% degradation of CPU performance relative to earlier releases. This is attributable to the Spectre/Meltdown security patches.

Note

For the procedure specific to SBC SWe upgrades on KVM Hypervisor or VMware to take advantage of performance improvements due to hyper-threading, refer to MOP to increase vCPUs Prior to Upgrading SBC SWe on VMware or KVM Hypervisor.

  • If you are using the SBC with a Broadsoft system and SBC is configured for registration access (where SBC sits between SIP phones and the Broadworks System. Otherwise no new REGISTER will be processed (phones will lose registration).
  • If you are using the SBC with other feature servers that require maddr processing.

Action to take: On the SIP trunk group facing Broadsoft (or other feature server), set the SIP Trunk Group signaling flag, honorMaddrParam, to enabled on the Trunk Group(s) requiring maddr handling. Default is ‘disabled’.

set addressContext <addressContext name> zone <zone name> sipTrunkGroup <TG name> signaling honorMaddrParam <disabled | enabled>

See the following pages for configuration details:

SBC SWe Pre-Upgrade Requirements

VM CPU resource allocation requirements

Starting with 4.2.4R0 release, CPU resource allocation requirements for SBC SWe VM are strictly enforced contrary to previous releases. You must review and verify these VM settings (including co-hosted VMs) against the documented "VM Configuration Recommendations" on the For VMware page in the Hardware and Software Requirements section before upgrading. If you encounter a problem, correct the CPU reservation settings as specified in step 6 of "Adjust Resource Allocations" procedure on the page Creating a New SBC SWe VM Instance with VMXNET3. CPU reservation should be set as “number of vCPUs assigned to VM * physical processor CPU frequency". If VM uses the same number of vCPUs as the number of physical processors on the server, this reservation may not be possible. In this case, reduce the number of vCPUs assigned to VM by one and set the CPU reservation to the appropriate value.

When using the show table system serverSoftwareUpgradeStatus command during the upgrade, the Standby server's LSWU status will always display "Upgrading" even though the upgrade may have failed due to host checker validation. To check if host validation failed for the Standby, check for HostCheck Validation Failed message in the upgrade.out log.

Disable Call Trace feature prior to LSWU/upgrade

As a prerequisite for SWe LSWU/upgrade, disable the Call Trace feature prior to performing the LSWU/upgrade and re-enable it once the LSWU/upgrade is completed.

Manually check for Hostcheck Validation Failed message

Perform the following procedure on the Standby to check for the Hostcheck Validation Failed message in the upgrade.out log.

  1. Log on to ESXi of the Standby SBC SWe.

  2. Check in/opt/sonus/staging/upgrade.out (this log shows the Hostcheck Validation Failed error).

  3. Power off the VM.

  4. Reduce the number of vCPUs assigned to VM by one and set the CPU reservation to the appropriate value.

  5. Power on the VM. The SBC SWe successfully upgrades to the latest version 6.2.0. 

  6. Run the command show table system serverSoftwareUpgradeStatus to confirm the successful upgrade.

  7. Perform similar procedure for LSWU on Active.

Preparing for Upgrade (All Platforms)

Warning

Prior to performing a Live Software Upgrade (LSWU), verify if the system and the databases are in sync. The steps are included in WBA "Warning-14-00020748". To view the WBA, log on to the Support Portal and click the Bulletins link from the menu bar. Enter the bulletin number (last eight numbers) in the search field and press Return.

Note

The SBC 7.2 release skips the SRV query if the flag in a DNS NAPTR response from the DNS server indicates to proceed with "A" record query as per RFC 2915/3403. This is a change in behavior from previous releases, where the SBC performed SRV queries irrespective of the "flag" setting returned by DNS Server.  If you use DNS NAPTR/SRV/A record query from SBC to determine peer transport address, ensure the DNS Server is configured to return ‘S’ flag to invoke an SRV query.

Note

In this release, LSWU infrastructure is added to the Platform Manager (PM) providing the ability to perform LSWU upgrades to later releases using the PM. However, this feature is not currently supported in 4.2.x releases and should not be used at this time.

Please read the following information and take necessary actions before starting your upgrade to this release.

Since the release 4.1.4, the cryptographic key pair used to sign and verify the package has been changed to enhance security. When installing/upgrading from all 4.0.x releases, all pre-4.1.4 releases (4.1.3 and earlier), and all pre-4.2.3 releases (4.2.2R00x and earlier), do one of the following, depending upon your upgrade method:

  • LSWU through CLI: Skip the integrity check during LSWU by using the CLI command below.

    During LSWU, use the integrityCheck skip option when upgrading from CLI:

    > request system serverAdmin <server> startSoftwareUpgrade integrityCheck skip package <package>
    Note

    Integrity check works as expected only when upgrades are started from 4.1.x releases (4.1.4R000 or later) or from 4.2.3R000 or later releases.

  • Upgrade through Platform Manager: If upgrading using Platform Manager, simply ignore the "Wrong Signature" warning message and continue the upgrade normally.
Note

Downgrading to any pre-5.0 release from this release requires a ConnexIP re-ISO installation. For more information, refer to:

Resolved Issues in 07.02.00R002 Release 

The following issues are resolved in this release:


Resolved Issues

Issue IDSevProblem DescriptionResolution

SBX-85187 / SBX-76066


2

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

The code was updated to match the IPv6 SRC IP address in the RTP packets so that a notification can be sent after the configured number of RTP packets have been received.

SBX-76501


2

The SIP Contact does not contain RegInfo with embeddedRegInfoinUserPart enabled.

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

1

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

Platform/Feature: SBC Core: Application

The code was modified to avoid the operation that caused the UserPart to be truncated.
SBX-852992

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.


SBX-852911

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

Platform/Feature: SBC CE: EMS

The buffer overrun was corrected.
SBX-770572

The SIPREC leg media changes to SRTP after the ingress leg of the CS call sends a re-INVITE.

Platform/Feature: SBC: Call Control

The code was modified to handle RE-INVITE cases when SRTP towards SIPREC is disabled. This takes care of both the INVITE and REINVITE cases whenever SRTP is supposed to be disabled towards SRS.
SBX-855552
When a 503 Error Response is received from MRF, MRFRM is not clearing its context. Calls are hanging towards the MRF Leg when FQDN is being used in the MRF Profile.

Platform/Feature: SBC CE: Media
The MRF context is cleared when 503 is received from MRF using FQDN.

Resolved Issues in 07.02.00R001 Release

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).

SBX-767323

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

Code was added for an unlimited callrate or bucket size scenario.

SBX-76829 / SBX-765002

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 CE: Redundancy

Code changes were made to generate an AMF_NODE_ARRIVE event in case of distributed (N:1) mode, so that NRS can process it and generate GARPs when the node is coming up in a standby role in the redundancy group. CHM handling of this event was also updated so that the northbound interface for the Cloud N:1 distributed mode is not disabled.
SBX-76862 / SBX-768612

PortFix SBX-76861: AIDE service is temporarily disabled as false alarms are generated.

Platform/Feature: SBC Core: Common Sonus Platform Services

AIDE is temporarily disabled to avoid false positives. Full implementation to provide user controls will undo this change.
SBX-76902 / SBX-742443

PortFix SBX-74244: ScmP core dumped due to a NULL pointer accessing a service group table entry.

Platform/Feature: SBC SWe: SIP

PortFix SBX-62682: Deleting the IP interface while in dryUp action causes an error.

Platform/Feature: SBC 5000/7000 Series: CLI, EMA, Platform IP/Media Services

The CLI warning was updated to inform the user about possible issues when deleting ipInterface in dryUp mode while active calls are taking place.


SBX-76919 / SBX-629172

PortFix SBX-62917: Configuration restore brings mgmtIntf4 interface to mgmtGroup.

Platform/Feature: SBC 5000/7000 Series: confd

The Active CHM process was enhanced so that is does not merge XML files received from the standby process in a CLI loadConfig scenario.
SBX-770362
Ingress trunkgroup stiProfile setting was assumed to be enabled and did not take into account that this setting might not be enabled. Therefore, the “null pointer" check was not in place, causing a coredump.

Platform/Feature: SBC Core: Application, SIP

The code was modified so that the setting was enabled and the core dump does not occur.

SBX-76495


1

The IKE process core dumped.

Platform/Feature: SBC CE: Application

The IKE timeout schedule callback function was updated to properly terminate and free the schedule structure, which prevents memory corruption from occurring.

SBX-76978


2

When the SBC has /var/log mounted on the external cinder volume, /home/sftproot/evlog is missing due to EMS stats collection failing.

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

The code was modified to replicate evlog dir on /home/sftproot/evlog, since /home/sftproot is the chroot directory for sftp access. 

SBX-76587

1

The S-SBC disconnects TCP connection after 60 minutes.

Platform/Feature: SBC Core: SIP-Peering

Based on the new configuration flag (sipTcpConnectionAgingState) if the flag is disabled, then every TCP connection in the SBC will be added in to the NON-AGING list.

Platform/Feature: SBC SWe, CE: DSP

The AMR and AMRWB improved the capacity code. Code was added, but channel density was not increased.


SBX-729292

The feature control flag is at IP peer level. Because of this, SIPFE goes for hash lookup to access Advance peer details for every call and the flag sits inside the peer.

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

The advancePeerControl flag was moved to Zone level from IP peer level. 

SBX-72970 / SBX-620833

The code was modified so that more than one URI cannot be configured.
SBX-73200 / SBX-731492

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

The Preconditions supported configuration issue where extra 18x is sent was fixed.

SBX-73360


3

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

The documentation was updated.
SBX-73434 / SBX-730402

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.


SBX-73475 / SBX-734172

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

SBX-73467 / SBX-727763

PortFix SBX-72776: Based on a coredump analysis, the openSSL stack was automatically clearing sessions resulting in corruption, triggering a coredump. 

Platform/Feature: SBC 7000 Series: Application

The code was modified to prevent the openSSL code from automatically clearing sessions.

SBX-73477 / SBX-73327

2

PortFix SBX-73327: A small window of race condition for a rare case of digit insertion causes NP to crash.

Platform/Feature: SBC 5000/7000 Series: Platform

The NP design code was modified to prevent the crash.
SBX-73602 / SBX-735732

PortFix SBX-73573: A dummy sessionDescriptionPtr was created in SIPSG and then passed to NRMA. NRMA uses the dummy sessionDescriptionPtr passed from SIPSG where sRTPAdminState is disabled, causing the SRTP late media call to fail.

Platform/Feature: SBC SWe: Media

The code was modified so that if NRMA receives a dummy sessionDescriptionPtr, it checks for the notFullyQualified flag. If notFullyQualified is set to TRUE, sessionDescriptionPtr is ignored.
SBX-73717 / SBX-685912

PortFix SBX-68591: The SBC reports "Policy Data syncInProgress".

Platform/Feature: SBC 5000/7000 Series: Install/Upgrade (Platform)

The change done by SBX-59731 was reverted as policyDBSyncStatus can have 600 permissions when generated by Oracle.

SBX-74059 / SBX-739553

PortFix SBX-73955: SipFe is not able to find registration, when the From header is missing the userpart, resulting in SipFe being unable to find the correct slot for routing the call.

Platform/Feature: SBC Core: SIP

The code was modified to allow SipFe to continue looking for registration based on src Ip/port.
 
SBX-74153 / SBX-731623

PortFix SBX-73162: Privacy is handled incorrectly in the outbound INVITE as the SBC sends a restricted userpart in the From header.

Platform/Feature: SBC Core: SIP

The code was modified so that the SBC sends out Anonymous@Anonymous.invalid in the From header.
SBX-74319 / SBX-740732

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

Platform/Feature: SBC Core: SIP

Code was added to support IPv6reference. 
SBX-74329 / SBX-742342

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

The code was modified to disable the packets NIFs to prevent ARP/GARPs from being sent from the becoming-standby before it restarts to become standby and after the active has sent GARPs
SBX-74332 / SBX-739132

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

When the SBC is brought down, the clean up script will leave the pkt ports at the "down" state at Linux level and also disable the pkt NIFs at the NP level. 
SBX-74338 / SBX-691372

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

The Kernel code was fixed so that memory allocated for IPSec Policy gets freed when the policy is removed from kernel by the application code.
SBX-74342 / SBX-741273

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.


SBX-74476 / SBX-727742

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

The code was modified so that there is audio after the call is set up.
SBX-74589 / SBX-743872

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

The code was modified to force SIPS to send the reINVITE.
SBX-74813 / SBX-734332

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

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

The NRMA call allocation function to initialize media port range values in the call leg structure was updated.
SBX-74857 / SBX-743752

SBX-74375: SCM cored as a result of an attempt to copy from unmapped memory. 
This problem is not predictable - but will only happen if sipSigSrvcGrpRewriteIdentities is configured. 

Platform/Feature: SBC 5000/7000 Series: SIP

The code was modified to prevent copying from unmapped memory.

SBX-74863 / SBX-736361

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

The code was modified to ensure service continuity in case of SBC double fault. 
SBX-75021 / SBX- 733912
PortFix SBX-73391: SCM process may coredump during multi-party redirection call flows.

Platform/Feature: SBC Core: Application

The code was modified to correctly define the size of the buffer used to transfer the peer active leg information, and copy the correct amount of data (from source to destination ICM messages).
SBX-75075 / SBX-745142

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.

The SBC is discarding media packets when the SBC is monitoring and media packets are received from IPV6 terminated peer.

Platform/Feature: SBC CE: Application

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.

SBX-850713

Problem Description

Impact/Workaround

SBX-74179


1

Cannot ping the G/W from the V6 interface alternatively when Alt_IP's are configured in X710 NIC card server.

Platform/Feature: SBC CE: Application, Platform

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


 1

The S-SBC is unable to register 1M endpoints with 1000 RPS and is having a 180 second refresh Register with RHEL 7.5, RHOSP 13 (Queens) setup.

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


2

The SBC does not add all codecs when Update is received with updated SDP from egress and sends 200 OK for Update with all supported codecs towards egress, the SBC is playing tone.

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

 4

Unable to commit pkt and sip-sig config with single commit command. An error message is thrown when the commit command is given.

Platform/Feature: SBC Core: CLI

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


 2

Unable to view TRAPS under Fault Management in Cloud-ISBC (Openstack Nova Platform) in EMS.

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

Impact: EMS will not be able to identify the trap since the source IP address is packet interface.

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

SBX-725132

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.

SBX-713032

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.

SBX-727362

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


2

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.

SBX-756092

The SBC VM is failing to join back the cluster post switchover after healing (Recreate_destroy) N:1 MSBC VM.

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

 Impact: The Ribbon VNF Manager provides functionality to manually heal a VM within an  orchestrated VNF.  There are a number of options for healing provided, including a Recreate_destroy option.  There is an issue if the Recreate_destroy is executed on a VM that has DHCP enabled on its interfaces.  In this case, the VM is provided new IP addresses, causing that VM to be unable to re-join in the cluster.

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

SBX-742692

The IPv6/v4 Interface update with a new dynamic meta Variable is not deleting the old IP address.

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.

set profiles media packetServiceProfile PSP_DM_DTLS rtcpOptions rtcp disabled


Known Limitations

The following limitations exist in this release:

  • Due to a known EMA GUI issue, it can take up to 10 minutes to process each SMM rule when provisioning SMM on the SBC using the EMA. This will be fixed in a future release.

  • The Access Control List (ACL) is not installed to configure SNMP traps for accepting traffic. A dynamic ACL is added to configure SNMP traps. An ACL must be installed for SNMP traps for accepting traffic.
  • The physical NIC connectivity must be in active state at the hypervisor level before starting the SWe instance on the SBC SWe platforms. In case of SWe instance with SR-IOV interfaces, manual restart of the SWe instance is required if physical NIC connectivity goes down while the instance is in progress.
  • The Antitrombone feature is not supported on the D-SBC.
  • EMS identifies the nodes based on the VNFC-ID. While instantiating SBC/PSX cloud nodes, ensure that you use a unique VNFC-ID only. If you reuse an existing VNFC-ID, EMS treats this as a re-registration request and overwrites the existing data on the cloud node.
  • While configuring the SBC SWe Cloud instances, the CLIs commits successfully even if any metaVariable provided is incorrect. The SBC SWe Cloud instance cannot validate the CLIs, as the CDB configuration file is stored in the SBC Configurator and is shared among all the other SBC SWe Cloud instances in the cluster.
  • Editing IP Interface is not reflected in the if configuration (ifConfig). This behavior is observed only on the S-SBC when action is set to "dryup" mode on the IP Interface. The IP address changes are not updated in the kernel and will not be displayed when ifconfig linux command is executed. In case of S-SBC, if the ipInterface configuration needs to be modified and if the action is set to "dryup" in ipInterface configuration, it must be set to "force" before disabling the ipInterface and making any changes.
  • A LSWU on an SBC 7000 should only be performed when the total number of active calls on the system is below 18,000. If the criteria is not met, a double failure during the upgrade may occur thereby losing all active calls. If such a failure occurs, both active and standby SBC services will go down.  Contact Ribbon Support immediately.

The VLAN tagged SRIOV packet interfaces are unable to ping endpoint Gateway IPs in the VMware platform because of an issue with VMWare.

Performing Heat Stack Update when userdata is Updated with SSH Keys

When upgrading SBC SWe cloud instances to release 7.2, you must update your Heat template userdata section to include mandatory SSH key information. An issue in OpenStack requires that you use the stack-update process rather than re-launch after updating the template, which leads to a new UUID for the instance. As a result, you must regenerate and apply new license bundles to the upgraded instances during the upgrade.

Refer to Upgrading M-SBCs in an N:1 Redundancy Group for the relevant procedure. 

Restricted Functionality with SBC

The following functionalities are not supported with SBC Microservices:

  • SRTP
  • Far end NAT traversal
  • DTMF inter-working
  • RTCP termination for pass-through calls
  • Direct Media and Antitrombone
  • NICE, SIP-REC
  • Rx, Rf interfaces
  • Multimedia - MSRP, BFCP  
  • Fax detection
  • ICE/STUN
  • SIP REFER
  • SIP REPLACE

  • Two stage calls

  • H323 support
  • GW signaling support

Restricted Functionality with SBC for AWS

The following functionalities are not supported with SBC for AWS:

  • The EC2 does not support VM console. The SSH must be used to access the VM.
  • The smarctl disk status is not supported on Amazon instance.
  • All the networking ports must be in different subnets.
  • The instance creation and reboot process take approximately 4 to 6 minutes to complete.
  • IP spoofing or L2 learning is not supported.
  • It is required to associate an EIP on MGT0 for an HA, and the CFN template automatically assigns the EIP. This is required for communicating with AWS servers while instance switchover. The EIP switchover takes 15-20 seconds.

Network Licensing Limitations

After switchover during grace period, when the new standby SBC comes up and establishes itself as standby, there is a short period (a few minutes) when the standby is synchronized for normal operation, but the new standby has not yet completed establishing its licensing state using the grace license information. If there is a second SBC switchover during that window, the new active SBC (which became active before completing license state synchronization) will lose calls until it re-acquires the grace licenses.

For configuring Network Wide Licensing, refer to Configuring Network Wide Licensing on D-SBC. This procedure is common for D-SBC and SBC.
