hi chen, Here is how i do it: # Route to PSTN Gateways(s) if (uri=~"^sip:9[0-9]*@XX.XX.XX.XX") { ## This assumes that the caller is log("Forwarding to PSTN\n"); ## registered in our realm strip(1); rewritehostport("PSTN-GATEWAY-IP:5060"); forward(uri:host, uri:port); break; }; On Jan 4, 2005, at 10:27 AM, Wayne Chen wrote: Srbo Cvetkovic | CityNet, Inc. srbo(a)city-net.com | Pittsburgh, PA voice: 412.481.5406 | fax: 412.431.1315

change the whole block with if(!lookup("location")).. to something like this: if(!lookup("location")){ if(uri =~"sip:2"){ route[..] break; }else{ sl_send_reply("404","Ha. not found"); break; }; }; The reason to do this, is with your if(!lookup.. you dont get down to the next ifsentence you have. so it will never hit it. -Atle * Wayne Chen <wayne.chen16(a)msa.hinet.net> [050105 05:03]: > Thanks for quick response from Srbislav. > I tried the same method, but still got "404 not found".
