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.

I have a problem with RTP and NAT.
The scenario is Hosted PBX and Natted phones (yealink):
Phones (192.168.0.x) - NAT -> FS (public IP)
When I call FS (for example an IVR) from a Phone, FS send the RTP to the private address (192.168.0.x) instead to the public NAT IP.
The registration is ok:
freeswitch@internal> sofia status profile tenant1.bs.dev.voip.clio.it reg

Registrations:

How I can tell FS to send the RTP Packets to the right address? I think is needed a "comedia mode" like in Asterisk (or RTPProxy in openser)...
Best regards,
