Hi, I want to know what should be the behaviour of UAC after receiving 180 response when dialog is already in confirmed state. I think it should process it, is this behaviour mentioned anywhere in RFC?
This scenario can occur in prepaid calling card application where user A first calls B, and after finsihing talking, he calls another user C on the same call. To connect user C, we can send Re-invite to user A agent resulting in call connected between A and C as per thirdparty call control. But before the call is answered by user C, if 180 Ringing is send to user agent A, it should play ringback as user need to hear the ringback to know the status of the second call. -Udit _______________________________________________ Sip-implementors mailing list [email protected] http://lists.cs.columbia.edu/mailman/listinfo/sip-implementors
