Conference room and video share

Hello All. I hope you are doing well.

Regarding conference room. I saw that there is two different way to implement it. with meetme and with confbridge. But in both there must be an admin and the users. It is not possible to implement something like skype? What I mean, going inviting people by calling them and in that way they get in the conference.

the people in the conference “room” can transmit video. The confbridge that I did is:

[general]

[admin_user]
type=user
pin=1260
marked=yes
admin=yes
music_on_hold_when_empty=yes
announce_user_count=yes

[default_user]
type=user
pin=123456
wait_marked=yes
end_marked=yes
music_on_hold_when_empty=yes
announce_user_count=yes

[default_bridge]
type=bridge
max_members=10
video_mode=follow_talker

But they can’t send video and the codec in the sip configuration is the same for the users.

Kind regards
