i’ve setup webrtc following guide: https://www.asterisk.org/asterisk-15-multi-stream-media-sfu/
test with ‘guestuser’ works fine but when i create user with freepbx with all the same parameters from guestuser but with name 602 (phone number) - in 30seconds after starting video-conference i see error: res_pjsip_sdp_rtp.c:146 rtp_check_timeout: Disconnecting channel ‘PJSIP/602-000000d8’ for lack of video RTP activity in 30 seconds.
need help please with user setup via freepbx 
Are you sure they are configured the same? What is the output of “pjsip show endpoint 602” in the Asterisk console?
yes, thank you. i’ve found differences. but i can’t correct them
added:
[602](+type=endpoint)
webrtc=yes
to pjsip.endpoint_custom.conf
tried also:
[602](+)
type=endpoint
webrtc=yes
reloaded dialplan, restarted asterisk.
but “pjsip show endpoint 602” still shows webrtc=no

can video-conference in asterisk work without webrtc? if so - can you point me to client softphone which support it (preferably non-paid)?
i’ve tried 3cx, microsip, linphone, phonerlite, blink and others which i don’t remember already
Asterisk doesn’t touch video, decode it, make a single “video conference” video stream, none of that. Any support for “video conferencing” would have to be done outside of Asterisk, such as by something establishing multiple SIP calls itself.
i was not asking for single conference video-stream. i need a softphone sip-client which can accept multiple video-stream from asterisk like “cyber mega phone 2000” from guide that i mentioned in first post here. and second question was: can it be done without webrtc?
I’ve never seen such support in a softphone, even though it is technically possible within SIP and SDP without WebRTC.
thanks. understood.
maybe someone else have seen such a miracle…
I have seen a Desktop Softphone (UDP-RTP) work with a single video stream - but failed when put into a SFU conference - or just showed a single video stream in any case. It was a long time ago - i think I used Zoiper or Linphone.
Mostly the inspiration for Siperb, among other things, was to accommodate for this kind of thing. UI wise, it can be tricky to accommodate N-many video streams. Not many of them are capable of doing it.
hello there 
i can confirm - linphone working that way. shows only one channel. and can sfu only on it’s own server with paid account
and siperb lacks cloud-independent application for now… but - yes, looks very promising
