Hi, I have a this call : * PROXY FS DEST* INVITE INVITE 100 Trying 100 Trying 183 SDP 183 Session P.SDP 480 Temporarily Unavailable 200 Ok DP ACK BYE When I receive a “ 480 Temporarily Unavailable” after a “183 Session Progress with SDP” FreeSWITCH tries to hang-up the call normally by sending a 200 ok and then a BYE response. But the call was not effectively established. It is generating problems in my proxy server. Is there a way to relay the 480 response or to change it to some other more accurate response.
