Hello I have an OpenSER which receives an initial INVITE request with a Route HF. It processes Route HF (by applying loose routing mechanism). Then it appends a new branch and relay the request. My problem is that the CANCEL request, which is generated by the TM module when a 200 OK response from the other leg was acknowledged, contains the original Route HF from the INVITE request, and not the processed Route HF. I think that the correct behavior is that the Route HF from the CANCEL request should not contains this proxy as topmost route. Thanks for any hints! Regards, MArius
