Hi All
Is 180 response received without TO tag a forked response? If the UAC sends an INVITE request and receives the first 180 response without TO tag and the second 180 response with TO tag Shall the second 180 response be indentified as forked response or not? Scenario: * UAC sends an INVITE request. * UAC receives 100 Trying and 180 response (without To Tag and with SDP, require: 100 rel, RSEQ) for Dialog 1. * UAC sends PRACK and receives 200 OK response for PRACK without TO tag. * UAC again receives 180 response with same SDP as in the last 180 response but contains a To-Tag for Dialog 2. * UAC sends PRACK and receives 200 OK response for PRACK with TO tag. As the initial 18x response was received with out a TO tag ,shall the next 18x response with TO tag be identified as a forked response ?
