[asterisk-users] RES: RES: How to dial extensions asynchronous-sequentially ?

[SamyGo]

If that is the case, why are you trying asterisk ? I suggest use SIP proxy
like Kamailio or OpenSIPS. When Call is initiated, create different
branches to different callee destination - this will place calls
simultaneously to the destination sides and will let everything coming from
the callee sides to the caller (multiple 100s,180, 183).

At that point you can extract all the info you need. Now regarding
establishing a video session and sending a video message before call gets
accepted is a whole new story.
