Is it possible to add a reason header in a CANCEL request? This is helpful in the following scenario: A call gets forked by the proxy (since there are more contacts for one AOR). On the of the SIP-destination-UAs accepts the call and sends a 200 OK to the proxy. The proxy afterwards generates the CANCEL request for all open UAC transactions. In this case it would be helpful to add additional infos, like "Call completed" elsewhere, so that the call is not listed in the "missing calls" list in the destinations UAs.

I've found a linke in the tracker on

http://sourceforge.net/tracker/?func=detail&aid=2581449&group_id=139... d=743023

Has this feature been included in the last official kamailio version, or is it still open.

Hello Andy,

i think this feature is still open. You might ask on the sip-router developer list ("sr-dev" sr-dev@lists.sip-router.org), perhaps the new TM module supports this already.

Regards,

Henning
