Section 1 indicates the following. "These call flows are based on the current version 2.0 of SIP in RFC 3261 [RFC3261] with Session Description Protocol (SDP) usage described in RFC 3264 [RFC3264]. Other RFCs also form part of the SIP standard and are used and referenced in these call flows." > Is support to handle forking response is mandatory > requirement for a SIP Caller [UAC]? Yes; RFC 3261 requires that the UAC know how to behave when forking results in multiple early/confirmed dialogs. However as discussed within draft-jesske-dispatch-forking-answer-correlation, some devices are non-compliant and some B2BUAs attempt to accommodate them. _______________________________________________ Sip-implementors mailing list Sip-implementors@lists.cs.columbia.edu https://lists.cs.columbia.edu/mailman/listinfo/sip-implementors
