[Serusers] t_relay results in 483 error

Hello, I am new to this list and SEr and am trying a very simple scenario. I would like to establish a call using SER via two grandstream BT100's(UA1 and UA2). The two agent and SER are all on public addresses. The two agents register with SER ok. However when I try to ring UA2 from UA1, I get a 483 error. I know that this mean there are too many hops. My config is practically the same as the basic (i.e. standard)configuration file (except for authorization and I have added a line including an alias equal to the public address of ser....the "if (uri==myself)" statement is correct I think...I checked). I checked the loopback address as suggested in the archives and can see that the invite is repeatedly sent to ser itself and 100 trying messages are sent to ser itself, therefore the max forwards value value must be reached and this is why the error occurs. I note that when I comment out all the t_relay()'s in ser.cfg, the error doesnt occur however the invite from UA1 reached ser and thats it.(i.e. its not forwarded)...Any help would be greatly appreciated(I run the most stable version of ser released i.e 0.8.14) Regards, Pat. ___________________________________________________________ ALL-NEW Yahoo!
