Hi Laurent,

You can either rely on Kamailio to do this using the mhomed=1 core config directive, more particularly described here:

https://www.kamailio.org/wiki/cookbooks/5.1.x/core#mhomed

Or you can turn this off, and manually steer outgoing requests by using the $fs PV. It is writable, e.g.

listen=udp:x.x.x.x:5060 listen=udp:y.y.y.y:5060

route[RELAY] { ...

$fs = 'udp:x.x.x.x:5060';

if(!t_relay()) sl_reply_error();

exit; }

If you are moving traffic between interfaces and using Record-Route, be sure to turn this setting on:

Dear all,

I have a config with multiple interface( multiple IP in same subnet) and want to know how I can select the interface used to send a request (UDP). The best is the possibility to choose for each request the outgoing interface but if it's not possible I think I can also work with a solution where the outgoing interface is defined globally ? I need this because one provider request one IP for inbound call and one IP for outbound call .

Thanks

Laurent
