Hello All,
I'm facing the following problem: An incoming call is first ringing on a call center queue: The UAS is sending a 180 Ringing with SDP and a require: 100rel, the UAC responds with a PRACK and the UAS again with an 200 OK. Then the call is actually ringing on a UA (IP hardphone) The UAS send a 180 Ringing again with an SDP and a require:100rel, but the UAC ignores this as is seems a duplicate message. ß INVITE/SDP supported: 100rel 100 Trying à 180 Ringing/SDP à Require: 100rel RSeq:1 ß PRACK 200 OK à 180 Ringing/SDP à Require: 100rel RSeq:2 180 Ringing/SDP à Require: 100rel RSeq:2 180 Ringing/SDP à Require: 100rel RSeq:2 180 Ringing/SDP à Require: 100rel RSeq:2 180 Ringing/SDP à Require: 100rel RSeq:2 Is the UAS allowed to send multiple 180 Ringing with a require header field?
