Media --------------UAS Gateway INVITE--------> <--------100 Trying <--------180 Ringing At this point, can UAS send a CANCEL to the media gateway? From the discussion in various mailing lists, I understand that UAS can not send a CANCEL request in this scenario. It can send a 4xx/6xx But, I could not find any RFC which talks about this. Could any one please provide info. on the RFC which talks about the above scenario? [ABN] in no case, UAS would cancel the CALL. It can only reject the call. If it can do away with failure response, why do you want to send new request ? You can refer sec 9. of RFC.3261 for more details...
