No audio and video

Asterisk Asterisk SIP
1

Sometimes there is no audio and video. I am using pjsip.

2

Far too little information to be useful. Lack of media is often the result of firewall or NAT misconfiguration.

Asterisk server is behind the NAT. My pjsip configuration file:
pjsip.txt (2.4 KB)

You are missing signalling and media addresses, and local networks.

Asterisk is a client, when making outgoing calls.

Attempt 3 to send STUN request to ‘x.x.x.x’ timed out. How to resolve this errror. In the firewall port 3478 is opened.

I’ve given

local_net=10.0.0.0/255.0.0.0
external_media_address=
external_signaling_address=

still no audio and video.

Do we need a TURN server when using asterisk?
