[Freeswitch-users] Freeswitch And 2 Network I/Fs

Is there an example of configuring Freeswitch to support both eth0 and eth1, when they are connected to different networks? I know I can create two sip_profiles, which works fine for registration, but in the past, I've had issues with Freeswitch not sending media to the right interface (or at least, not knowing how to control that). Thanks, Jerry
