I have configured the Asterisk server in a docker image and it's running, I have also configured the STUN/TURN server and it's also running on the same virtual system.
Now, I try to connect my extensions but they drop after 10-15 mins if connection and don't connect after that.
The TURN server is a CoTURN server : https://github.com/DreamNetwork/docker-coturn/blob/master/Dockerfile
The VOIP server is an Asterisk 12 server with FreePBX as the frontend. I am doing my configurations on the freePBX.
Initially, I was not able to connect which led me to setup the STUN server and even after that, I am not able to progress... Can anyone tell me what I can do to over the NAT, because if I setup a mobile-hotspot all connections work fine without STUN.
