[SR-Users] kamailio as sip router and rtp proxy without reg on kamailio

Wed Feb 5 19:10:40 CET 2014

Read the default configuration to understand how routing within Kamailio 
works.

Regarding REGISTER: just remove all the REGISTER handling (and PUBLISH, 
SUBSCRIBE and NOTIFY) in the config, then the REGISTERs will be routed 
like all other messages.

Then take a look at the PSTN gateway feature. Use this (or similar) to 
route the calls to Asterisk (just do not analyze the userpart if it is a 
phone number but handle all requests like PSTN calls and send them to 
the gateway (-> the Asterisk server).

Further, use 2 listen statements:
listen=udp:external-IP:port
listen=udp:internal-IP:port

When sending from internal to external (or in the othe direction) use 
the force_send_socket() to force the proper outgoing socket.
