[Freeswitch-users] RTP NAT issue

[Brian Foster]

The issue is more likely the phone, as the phone is responsible for handing
FS the correct IP. There is however a way to force this on the FS side but
may break other devices. Please take a look at NDLB (No Device Left Behind)
parameters for Sofia on the wiki.
