|Description:||This is an enhancement for SIP.|
I was thinking about this scenario: incoming call from a SIP UA into asterisk. Asterisk answer the call with early media ("183 - Session Progress" instead of "200 OK"). An IVR will figure out the destination of the new call and once the destination is known, the call is terminated via the "Transfer" application (a 302 will be generated back to the caller).
Maybe this could be easily implemented by enhancing the Answer application via a parameter that will instruct the SIP stack to generate a 183 instead of a 200.
The "Transfer" application already generates a 302 for calls that are in progress.
This will reduce the stress on asterisk for high number of incoming calls - no need to maintain the state of the call after the call was transferred.
