I have Kamailio 5.1 installed and running with 2 extensions, 201 and 202 registered. Both extensions can call each other perfectly.

Next I am workin on inbound calls.  I have an inbound call from a carrier that arrives perfectly but ends up in this area of the cfg

case -3:
                                send_reply("404", "Not Found");
                                exit;

and sends a 404 not found. 

How do I :
  1. Associate the 10 digit DID to the 201 or 202? Custom table I make or is there something native to Kamailio. 
  2. Relay the call to the 201 or 202. 
Thank in advance
