Parameter

Description

Internal Cause

Specifies the option to configure custom SIP cause response codes. Options are:

  • Congestion Policing  – 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 SIP response. The Retry-After value is randomized between 'retryAfterMin' and 'retryAfterMax' values. The 'retryAfterMin' and 'retryAfterMax' values must be configured under Ingress Trunk Group in CLI. Refer to sipTrunkGroup congestionHandling SIP Trunk Group - Congestion Handling - CLI to configure these parameters.
     
  • Other Req Rate Policing – Cause code when a message rate other than REGISTER or SUBSCRIBE exceeds IP trunk group's maximum configured value.
  • Register Rate Policing  – Cause code when REGISTER message rate exceeds IP trunk group's maximum configured value.
  • Register TGLimit – Cause code when current REGISTRATION exceeds IP trunk group's maximum registration limit.
  • Register Timeout – Cause code from REGISTER request timeout.
  • Subscription Rate Policing – Cause code when SUBSCRIBE message rate exceeds IP trunk group's maximum configured value.

  • Subscription TGLimit – Cause code when current Subscription on IP trunk group exceeds maximum configuration limit.

Sip Cause

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 value ranges from 300 to 606.
