Your choices are either to let Kamailio do that, or set mhomed=0 and choose the egress interface manually based on your own criteria. You can do this by setting $fs prior to t_relay(), e.g.
$fs = 'udp:x.x.x.x:5060';
Bear in mind that this combination of transport, listener and port must correspond exactly to one of the listeners.
It sounds like that's what you need to do.
