Hi Andreas, Thanks for the reply, I was thinking of another approach to do this, tell me if I am wrong. May I use the 'phone' field in subscriber table to run an external sql script to map the DID (phone) with a username, and then rewrite the uri, and then forward the call to that user?

Hi, I assigned the DID to the user but serctl add alias, and the entry got updated in ser.aliases table. But when I call the number from pstn, the registered user does not get the call. The nextone contacts the SER, but SER responsds to it with a "478 unresolvable desintation". Following is the ngrep excerpt. U PSTN_GW_IP:5060 -> SER_IP:5060 INVITE sip:@SER_IP SIP/2.0.

Relevant code from ser.cfg is as follows: ... ... modparam("usrloc", "db_url", "mysql://ser:heslo@localhost/ser") modparam("usrloc", "db_mode", 2) if (uri==myself) { if (method=="ACK") { route(7); break; } else if (method=="CANCEL") { route(3); break; } else if (method=="INVITE") { route(3); break; } else if (method=="MESSAGE"){ route(4); break; } else if (method=="REGISTER") { route(2); break; }; lookup("aliases"); if (uri!=myself) { route(5); route(1); break; }; if (!lookup("location")) { sl_send_reply("404", "User Not Found"); break; }; I don't know where I am wrong.
