      Status: Waiting for Feedback  (was: Triage)

Can you try a basic scenario with just Asterisk and client by a simpler setup or following the instructions on this wiki page [1] to see if the problem is reproduced there as well? This is just to eliminate possibilities of what might be causing the problem. It does look like there may be an issue with requesting a topology change; I'm curious to see if the same happens here.

> After Asterisk upgrade from 16.9.0 to 16.20.0, we began to experience problems with the application when creating ConfBridge conference rooms for 2+ participants. Video streams for some participants do not appear.

> 1. Add first user to the conference:
> POST http://asterisk.node:8088/ari/channels
> {"endpoint": "PJSIP/81014504875 at webrtc", "callerId": "<8007709999>", "context": "conference_room", "extension": "create", "variables": {"conf_name": "conference_room_37368", "formats": "opus,vp8" ... }
> 2. Add other participants. For example:
> POST http://asterisk.node:8088/ari/channels
> {"endpoint": "PJSIP/81014504876 at webrtc", "callerId": "<8007709999>", "context": "conference_room", "extension": "add_member", "variables": {"conf_name": "conference_room_37368", "originator": "37368" ...}
> Where "originator": "37368" - first user's channelId
> {code}
