I am attempting to have SER act as a local registration server, that forwards all registrations to another SIP Registrar/Proxy that routes calls to the PSTN or wherever they go. The second server also does the call accounting. The reason that the SER server forwards all registrations to the second server is in case incoming calls match a registered SER user that is logged on, make sure they get routed correctly.

I also need to make sure any BYEs and CANCELs get forwards to end calls in a timely manner.

Can someone take a few moments to tell me what I am doing wrong? Calls are being forwarded corrently if they are not to a local SER user, but if they go from the SER server back to another SER registered user, the client hangs at "Connecting" and the following debug is given in SER.

Please dont laugh at any major mistakes in my ser.cfg, I am not a newbie to VoIP, I seem to have problems following the routing logic.

Thanks, Doug
