[Freeswitch-users] fs_nat=yes on webrtc connection

[Maximilian Leonhard Dorn]

Hi everyone,

I am currently working with sip.js and freeswitch which is currently connecting to our freeswitch via the our internal network.
Looking at the registration I am seeing that the contact show fs_nat= yes. Here the registration from the server.

Nat detection is disabled for the freeswitch and a normal snom phone registering to the server does not show the fs_nat=yes
Does freeswitch always detect nat for webrtc connections? Or is there possibly something wrong in my configuration?

Kind Regards,
Max
