The purpose of the Ring Timeout timer is to terminate a call received on a Termination Customer Trunk Group that has not received a final response (e.g. a SIP 200 OK) from a vendor within the configured timeframe.
This timer is only applicable to Termination Customer Trunk Groups and starts when a SIP Invite is received at the Termination Customer Trunk Group. The Ring Timeout Timer stops when a final response is received from the vendor. If the Ring Timeout timer expires the orchestrator will send a SIP Cancel message to the vendor and a SIP 504 PDD Timeout response to the customer.
If configured, the timer must have a value between 1 and 240 seconds. If the timer is not configured, it will have a value of 240 seconds.
