This is two-way video/audio; in other words a two-way video call. So if we set this number at <timeout_connected>3600</timeout_connected> this will affect only the video/audio call and not voice only calls? I guess I'm still a little confused as to what this number controls.
One of the tests that we conducted this morning was to establish a normal audio-only call. After about 5-6 minutes on the same call, we switched on the cameras, exactly 120 sec later the call dropped, both audio and video.
