So if I use the t_cancel_callid function, Kamailio sends a CANCEL to the UAS, but doesn't send anything to the UAC? Or do I need to handle that myself?

Alex, Who sends a CANCEL on a fork? ;-) That's the proxy's job. (Sorry could not resist) But you are right that if you cancel ALL branches in the proxy so that the UA suddenly gets a 487 and is not aware of the CANCEL that can be messy. /O _______________________________________________ SIP Express Router (SER) and Kamailio (OpenSER) - sr-users mailing list sr-users@lists.sip-router.org http://lists.sip-router.org/cgi-bin/mailman/listinfo/sr-users _______________________________________________ SIP Express Router (SER) and Kamailio (OpenSER) - sr-users mailing list sr-users@lists.sip-router.org http://lists.sip-router.org/cgi-bin/mailman/listinfo/sr-users
