Hello. I would like to know whether Asterisk can be configured to be used for Video conference purposes.
For conferencing, you could use ConfBridge, this also supports basic video conferencing, though this feature is currently considered experimental.
This thread might be interesting for you viewtopic.php?f=1&t=96315
You can use app_konference
but it doesn’t mux the video streams, it can only play audio from all participants and choose by hand which one to view.
