I am forced to use pjsip , but I really don’t know how to configure pjsip extension for NAT.
My pbx is using internal IP address 192.168.254.199 and it is behind a router which has public dynamic IP address.
should I use stun ?
how can I configure the extension so that it is working with bi-directional RTP ?
I am using Asterisk 13.17.1 with FreePBX.
with the default pjsip extension config, I don’t see any RTP packets to the IP address in the sdp header from the client.
