ACK is directly sent to UAS and if your proxy has added Record route, ACK would come to your proxy bypassing previous proxies and in that case u may get different Via and branch.
Is the Via header same? Vivek -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Markus Hofmann Sent: Thursday, February 17, 2005 8:18 PM To: [email protected] Subject: [Sip-implementors] Right behaviour of a SIP proxy by unexpected ACK Hello, our proxy was receiving and forwarding an INVITE. The UAS answers with a 180 Ringing which the proxy forwards. But now the UAC sends an ACK with a different Via branch to the proxy - the Call-ID, To-Tag, From-Tag, CSeq, everything is right. What should be the right behaviour from the proxy. Drop it or forward it. At the moment I don't find the answer in RFC 3261. Thank you in advance.
