[SR-Users] Public vs Internal IPs

[Colin Morelli]

Thanks for the quick reply!

Binding to two SIP ports isn't out of the question (though I'd like to
avoid it if possible).

However, with this approach, I assume somewhere I must have to instruct
Kamailio which outbound interface to use (i.e. tell it to use 5080 for
forwarded requests to internal hosts and 5060 for requests headed out?) How
else would it know to cross over the interfaces?

Best,
Colin
