When we are sending calls to another provider who are using Openser, they are not taking the contact address from our 200 replies, instead they are putting our Openser address in the RURI of all Acks, Byes and Cancels. Am I right in saying that this is incorrect? Im not sure where they are getting this address either, maybe from the To: field, or from the record route header? <br><br>Is there a way to match the message received to a transaction and route the message to the contact in the original invite stored by TM? Or perhaps some better way of solving this?<br><br>Here are the messages:<br><br>SIP/2.0 200 OK<br>Via: SIP/2.0/UDP xx.xxx.0.33;rport=5060;received=41.221.0.33;branch=z9hG4bKb9fc.f1cf4e03.0<br>Via: SIP/2.0/UDP
