>From an RFC perspective, the UAC must support INVITE forking interactions (i.e. potential for multiple early/confirmed dialogs). However as discussed within draft-jesske-dispatch-forking-answer-correlation-03, not every UAC is compliant. > Is this the desired behavior as per the RFC? Yes; support for forking is not optional within RFC 3261. Similarly, RFC 3262 section 4 indicates the following. "The provisional response MUST establish a dialog if one is not yet created. Assuming the response is to be transmitted reliably, the UAC MUST create a new request with method PRACK. This request is sent within the dialog associated with the provisional response (indeed, the provisional response may have created the dialog)." _______________________________________________ Sip-implementors mailing list Sip-implementors@lists.cs.columbia.edu https://lists.cs.columbia.edu/mailman/listinfo/sip-implementors
