Use this object to configure custom SIP cause response codes.

  • 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.

 

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

sipCause300-606Specifies 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.
sipCauseText0-127Specifies the Internal Sip Cause text that is used in the Reason Header of the error response to reject the SUBSCRIBE Request.
