Hello All,

I can setup my SIP Trunk in 3CX, but I'm failing to locate in these forums how to dial from 3CX to my Grandstream UCM6202
-I'd like to go extension to extension (video to video)
-I tried 3CX years ago, never got it to work, so I'm circling back and trying to get this older UCM to work.

Also, what I'm really after is site-to-site:
I'd like at one site to use 3CX extension to the other site w/Grandstream UCM6202 (hoping extensions I setup in 3CS can be added to Grandstream's extensions), or a way they can see each other.
-Not sure if this is a 'linked option' or 'a bridged' setup, or...

If there are PDF's I can use here, that would be great.
-I think my issue is nomenclature, I just don't know what this option is called.

Thanks all!
