No no no.
In most situations (99%) you don't need STUN.
There are 2 ways to defeat NAT:
-a client way (STUN) where the client endpoint is going to send a corrected INVITE
-the server way (often called Autolearn, NAT autodetection, ...) where the rtp forwarder waits for inbound RTP coming into the port it opened for the call, and then uses that IP:port to send back the opposite stream

FreeSWITCH implements autolearn (rtp-auto-adjust) and it is quite excellent.
