[Freeswitch-users] Phone not registering

[Michael Collins]

You just have to be careful because the force rport can mess up phones that
properly handle NAT. If you plan to use only this model of phone - or only
phones that require force rport - then you'll be fine. If you find that you
have a mix of phone models then it's best to create a separate profile to
handle phones that are NAT friendly and then keep the current profile for
phones that need the force rport.
