Hello List. My test settings are as follows - [UA-1]-------[ser + mediaproxy 1]--------------[ser + mediaproxy 2]-----------------[UA-2] I have the following setup in both the ser.cfg files (ser 1 and ser 2) - ----------------------------------------- if (method == "BYE" || method == "CANCEL") { end_media_session(); } ----------------------------------------- However it appears that when UA2 ends the call, SER 2 calls end_media_session() - but SER 1 doesn't. When UA1 ends the call, the opposite happens. Shouldn't both the SERs be calling the end_media_session()? Thanks for any feedback. Regards, Dhiraj
