Question regarding VoIP and hybrid systems
I'm just scratching the surface of testing out a VoIP system at school based on trixbox. I have this set up, and have added two extensions using softphones on a couple of Macs. I'm also getting hold of a couple of 2nd hand hardware phones just for the sake of it.....
My question is, how do I connect the trixbox server in to the current phone system? This is not something we will be doing straight away as it is purely a test set-up at the moment. I read something about an FXO card, but I couldn't find much of an explanation of what this is, or what it does, or how it connects! What do I need to build or buy to be able to call from an IP phone, to a "real" phone on our Samsung DCS system, or from an IP phone to the outside world?
Any advice is welcome!
