Use this feature to configure specific SIP response codes to particular internal SIP request rejections from SIP Service Group.  

Command Syntax

% set profiles signaling sipCauseCodeMapping internalSipCauseMapProfile <profile_name> causeMap 
	congestionPolicing sipCause <300-606> 
	otherReqRatePolicing sipCause <300-606>

Use following CLI syntax to attach an Internal SIP Cause Map profile to a SIP trunk group. 

% set addressContext <addressContext_name> zone <zone_name> sipTrunkGroup <TG_NAME> signaling causeCodeMapping sipInternalCauseMappingProfile <profile_name>

Use following CLI syntax to attach an Internal SIP Cause Map profile to a zone.

% set addressContext default zone INGRESS_ZONE causeCodeMapping                                                                            
Possible completions:
 sipInternalCauseMappingProfile - The name of internal cause to SIP mapping profile                                          

% set addressContext default zone INGRESS_ZONE causeCodeMapping sipInternalCauseMappingProfile <sipInternalCauseMappingProfil>

<profile name> – Internal SIP Cause Map Profile name.

causeMap

N/A

Use this object to configure custom SIP cause response codes.

  • Peer Bidirectional Blocked - SIP cause used when the peer has the bidirectional blocked.
  • Peer in Disabled State - SIP cause used when the peer is in disabled state.
  • Peer Incoming Blocked - SIP cause used when the peer has the incoming calls blocked.
  • Peer Outgoing Blocked - SIP cause used when the peer has the outgoing calls blocked.
  • Peer Out of Service - SIP cause code used when the peer is out-of-service.
  • Trunk Group Bidirectional Blocked - SIP cause code used when the trunk group has the bidrectional calls blocked.
  • Trunk Group in Disabled - SIP cause code used when the trunk group is in disabled state.
  • Trunk Group Incoming blocked - SIP cause code used when the trunk group has the incoming calls blocked.
  • Trunk Group Outgoing blocked - SIP cause code used when the trunk group has the outgoing calls blocked.
  • Trunk Group Out of Service - SIP cause code used when the trunk group is out-of-service.
  • congestionPolicing sipCause <value> – SIP cause code used when an initial SUBSCRIBE request is rejected due to Adaptive Overload Control. This internal cause code is mapped to 503 by default, and a Retry-After header is added to it. The Retry-After value is randomized between 'retryAfterMin' and 'retryAfterMax' values.
  • otherReqRatePolicing sipCause <value> – SIP cause code when a message rate other than REGISTER or SUBSCRIBE exceeds IP trunk group's maximum configured value.
  • regRatePolicing sipCause <value> – SIP cause code when REGISTER message rate exceeds IP trunk group's maximum configured value.
  • regTGLimit sipCause <value> – SIP cause code when current REGISTRATION exceeds IP trunk group's maximum registration limit.
  • regTimeout sipCause <value> – SIP cause code from REGISTER request timeout.
  • subsEndPointRatePolicing sipCause <value> – SIP cause code to map SUBSCRIBE Endpoint CAC default error response.

  • subsRatePolicing sipCause <value> – SIP cause code when SUBSCRIBE message rate exceeds IP trunk group's maximum configured value.

  • subsTGLimit sipCause <value> – SIP cause code when current Subscription on IP trunk group exceeds maximum configuration limit.

 

sipCause300-606

Specifies the response code to use when a received SIP message other than an INVITE or a REGISTER is rejected due to congestion in the SBC.

The sipCause range for the above cause codes is 300-606.

sipCauseText0-127Specifies the Internal Sip Cause text that is used in the Reason Header of the error response to reject the SUBSCRIBE Request.
