Command Parameters

SBX-62459 Support for Public-key-Based Peer Authentication Method for IPSec

The SBC is enhanced to support a Public Key-based peer authentication method for IPSec on SBC. In past releases, the SBC used a Preshared key-based authentication method for Peer authentication during IKE negotiation for establishing IKE and IPSec Security associations. To meet Common Criteria certification requirements, the SBC is now capable of using x.509 digital certificates for Peer authentication. Note: Not currently supported on SBC Cloud and D-SBC platforms.

For more information, refer to IPsec Peer - CLI.

Command Syntax

% set addressContext default ipsec peer <peerName> authType <psk | rsaSig>
% set addressContext default ipsec peer <peerName> localCertificate <sbcCertName>
% set addressContext default ipsec peer <peerName> remoteCertificate <peerCertName>
% set addressContext default ipsec peer <peerName> remoteCaCertificate <caCertName1>

Command Parameters

SBX-67554 LCQ CC/SIP Issue - Multiple Call Transfer - SIP Layer Stops Responding

The SBC is enhanced with the parameter maxNumTransfers under the object global signaling.

For more information, refer to Signaling - Global - CLI and Show Table Global.

Command Syntax

To configure maxNumTransfers, use the following syntax:

% set global signaling maxNumTransfers <10-100>

Command Parameters

Configuration Examples

To configure maxNumTransfers, use the following example:

% set global signaling maxNumTransfers 30

To display the maxNumTransfers, use the following example:

• In the "configure" mode:

  Code Block
  % show global signaling maxNumTransfers maxNumTransfers 30

  
  

• In the "display" mode (when you exit the "configure" mode):

  Code Block
  > show table global signaling maxNumTransfers 30; messageManipulation { inputAdapterProfile DD1; outputAdapterProfile DD1; } sipPeerOverloadControl { samplingPeriod 2; discardPeriod 2; stepDownGain 100; rejectThreshold 1; } sipSigControls { registrarSupportContactParam enabled; maxPduSizeValue pdusize15kb; }

  
  

SBX-68878 CDR for SIPREC Sessions

The SBC is enhanced to support a new parameter "Generate Recording CDR" to the OAM > Accounting > Admin. When the "Generate Recording CDR" parameter is enabled, the SBC generates a Recording-CDR. The selected CDR is placed in the .ACT files along with the other call and Event CDRs. All the file size and CDR count rules of the existing CDRs apply to the Recording CDRs. 

For more information, refer to Packet Service Profile - CLI.

Command Syntax

% set oam accounting admin generateSipRecordingCdr <disabled | enabled>

 Command Parameters

SBX-70465 STIR/SHAKEN: Option to Signal Verification Failures in Backward Provisional Responses

The ATIS specification defines an optional capability to signal verification failures in backward provisional responses. If a terminating carrier B fails verification for an originating carrier A subscribers, but continues to deliver the call to the carrier B called party, carrier A will have no way to know. The terminating carrier can use failed verification to indicate robocalling status to the called party. In this case, carrier A has no way to know that their subscribers' calls are being flagged as robocalls to the terminating party.

The capability described in the ATIS specification solves this issue if carrier A has tools in place to find these indications in the SIP messaging.

Trunk-group-level SIP cause value reporting should include counts for each unique case value transmitted. These statistics already exist for the Reason header transmitted at the end of the call; however, this would additionally count the cause values send in the 18x/200 for STIR/SHAKEN.

New STI Profile flag overWriteReasonCodeIn4xxto6xx added regarding 4xx-6xx handling.

For more information, refer to STI Profile - CLI.

Command Syntax

% set profiles services stiProfile <profile_name> overWriteReasonCodeIn4xxto6xx <disabled | enabled>

Command Parameters

SBX-70938 RTCP for T.140 Pass-through

A parameter, t140RtcpMonitorInterval, is added under mediaRTCPControl to define the RTCP monitoring interval. This enables the SBC to wait for an RTCP packet from peer before starting RTCP towards T.140 endpoint with the following PSP flag enabled.

% set system media mediaRtcpControl t140RtcpMonitorInterval 6
% set profiles media packetServiceProfile DEFAULT rtcpOptions generateRtcpForT140IfNotReceivedFromOtherLeg enable

Command Parameters

SBX-75174 - Generate or Replace SSRC Values for Calls Toward a Kandy Link WebRTC Gateway

The synchronization source (SSRC) identifier uniquely identifies media streams within an RTP session and is included in SDP signaling when establishing or modifying media sessions. The WebRTC specification requires that the SSRC value in an RTP stream match the SSRC sent in the SDP. However some endpoints, such as PSTN gateways, are not capable of generating SSRC values so they are not present in the SDP. Other endpoints change the SSRC during call hold/resume scenarios. The SBC provides two flag parameters to the Packet Service profile to determine whether the SBC generates and updates the SSRC and related attributes.

For more information, refer to Packet Service Profile - CLI.

Command Syntax

The SBC adds the following two flags to the Packet Service profile. 

% set profiles media packetServiceProfile <profile name> flags
      generateAndSignalSSRCAndCname <disabled | enabled>
      allowMidCallSSRCModification <disabled | enabled>

The SBC only allows mid-call modifications to the SSRC if it is generating the SSRC. Therefore, the first parameter, generateAndSignalSSRCAndCname, must be enabled for the second parameter, allowMidCallSSRCModification, to become available.

Command Parameters

SBX-75865 Alarm Generation when SBC Receives RCODE Except for 0

The rcodeErrorMonitorTimer parameter is added to the DNSGroup configuration to support monitoring timer interval which the SBC Core uses to monitor RCODE errors.

 For more information, refer to DNS Group - CLI

Command Syntax

% set addressContext <address_context_name> dnsGroup <dnsgroup> rcodeErrorMonitorTimer <rcode_error_monitor_timer>

Command Parameters

SBX-76436 - Increase CDR Retention with Compression

The SBC is enhanced to allow writing accounting files containing CDRs into a compressed format. The compressed files are retained for a user-specified time period; thereafter, they are automatically deleted after a specified number of days. The compressed files are stored in the evlog directory or another directory that you specify.

 For more information, refer to Event Log - CLI

Command Syntax

% set oam eventLog typeAdmin acct
    compressionSupport <both | none | only>
    compressionDaysToKeep <1 .. 7>
    compressionCleanupDirectory

% set addressContext default zone <zone_name> sipTrunkGroup <siptrunkgroup_ingress_name> signaling performPrecondtionRenegotiation 
<enabled | disabled>

Command Parameters

SBX-86008 Cloud SBC Avalanche Fault - Detection and Control

Packets that cause a direct SBC fault can lead to a catastrophic failure of an SBC service, which is known as a packet-stimulated fault avalanche. These packets appear for various reasons, such as: the SBC adds a new Session Initiation Protocol (SIP) endpoint, upgrades or replaces a peering endpoint or gateway (GW), changes a configuration on a peer, or introduces a new call scenario. The SBC does not currently check for double faults, which is when the SBC has a failover and then another failover. Double faults cause call loss.

For more information, refer to  CLI Configure Mode.

Command Syntax

Use the following command to set and configure the faultAvalancheControl parameter.

% set system faultAvalancheControl callIdThreshold <0-999> calledPartyThreshold <0-999> callingNCalledPartyThreshold <0-999> callingPartyThreshold <0-999> sourceIpThreshold <0-999> faultRecAgeingTimeOut <15-60>

Use the following command to enable or disable the faultAvalancheControl parameter.

% set system faultAvalancheControl facState <disabled | enabled>

Command Parameters

SBX-86658 Offer-Answer Timer Configuration

In specific call scenarios, the SBC treats the Offer-Answer (OA) as a MODIFY Offer-Answer cycle, but the peer treats it as an INITIAL Offer-Answer cycle. According to RFC 3261, the response from the peer is expected within 300 seconds. The SBC, however, assumes a 20-second response, and therefore any delay in the response from the peer which exceeds of 20 seconds causes call failure.

Currently, the internal Offer-Answer (OA) timer value is fixed and cannot be configured. To overcome this limitation, the SBC is enhanced with a new parameter offerAnswerTimer to configure this OA timer.

For more information, refer to Signaling - Global - CLI

Command Syntax

% set global signaling sipSigControls offerAnswerTimer 
Possible completions:
<Enter offer answer timer value in range of (10..300) in seconds.> (20):

Command Parameters

SBX-86789 SBC Should Create TLS Connection Based on Contact Header
