Setting up Asterisk and webrtc

xspander · February 12, 2024, 4:04pm

Can anyone help me configure Asterisk to work simultaneously with local video intercom panel “Bas IP” and clients connecting via webrtc? When calling from a browser there is a connection, sound in both directions, but no video.

Nginx has SSL certificates installed and clients connect without problems

I use last version of Asterisk (20.6.0), use Nginx to reverse proxy, and Kerio VPN client to connect the server with video intercom panels into one VPN network.

Maybe there is something in the configuration files that I missed?

Here are my config files:

What do the INVITE and its response (the SIP packets containing the SDP)
contain?

Or the SRTP is otherwise corrupt.

xspander · February 14, 2024, 11:16am

Does this sound like there is a problem with the intercom video panel?

InnovateAsterisk · February 14, 2024, 12:15pm

I have experienced the same problem, or sometimes I get a second or two of video before this occurs.

The error was being raised in res_srtp. Yes, this is a part of SRTP. It may not be corrupt, but out of date.

In my case, I didn’t trace down my error, I’m yet to solve the issue.

xspander · February 14, 2024, 6:23pm

I was just trying to set it up according to your guide, calls between webRTC clients go through without problems, but there is a problem with the intercom

xspander · February 14, 2024, 6:29pm

I noticed that when the webRTC client tries to receive a video stream from the intercom panel, many “INFO” requests come with the same content
