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 SIP Trunk Group - Congestion Handling - CLI to configure these parameters.Other Req Rate Policing – Cause – SIP cause code when a message rate other than REGISTER or SUBSCRIBE exceeds IP trunk group's maximum configured value.Register Rate Policing – Cause SIP cause code when REGISTER message rate exceeds IP trunk group's maximum configured value.Register TGLimit – Cause SIP cause code when current REGISTRATION exceeds IP trunk group's maximum registration limit.Register Timeout – Cause SIP cause code from REGISTER request timeout.Subscription EndPoint Rate Policing – Cause SIP cause code to map SUBSCRIBE Endpoint CAC default error response.Subscription Rate Policing – Cause SIP cause code when SUBSCRIBE message rate exceeds IP trunk group's maximum configured value.
