Hi, I want to configure SER as a proxy server. I would like SER to proxy presence messages and I have done that with the help of record_route and t_relay_to_udp. I would like to have SER forwarding the register message to another server to authenticate and after successful authentication SER store the location to route the requests. I observed SER is not allowing URI getting registered. I tried the following but did not work.. if(!uri==myself) { if( method=="REGISTER") { record_route(); save("location"); t_relay_to_udp("132.146.109.243","5060"); break; }; }; Can anyone let me know how can I enable other domain URI passing through SER to reach other server which authenticates them? Thanks and Regards, Senthil Kumar,
