I have been struggling with asterisk from last few weeks. There are certain features which are supported in 3CX
but looks like asterisk is not supporting it. Previously I was trying to get the video from the monitor before answering the call (3cx support this feature by default), I posted this question here but couldnt get much support. Well I have figured it out by myself using “hit and trial” method and now I am getting pre-video in my SIP monitor.
Now I want to call ring group where 2 monitors will ring simultaneously, and I want pre video feature for it. I am surprised that it works with one SIP video monitor, but when I dial the ring group (with two sip extensions), I dont get the video before answering the call. I only get video once the call is answered.
3CX again support this feature by default, we dont need to configure anything, I believe there must be some options for asterisk as well.
I need this feature for my video door entry system, it is a big project, and I want to solve it for my customers
Is there anyone who has worked on this kind of project before ? Any help would be much appreciated
thanks in advance
