We have been using NexVortex lately with good results. Recently, a company called me called Nextiva. They provide a trunk - with 1 call path - unlimited calls - for a fixed price per month. They say that if I am on the phone and get an incoming call that that phone will ring if it has another line instance programmed. Is this correct? Or would the call come into the PBX? I would think 1 call path per trunk means just that - and no more calls would pass. I am thinking I need to test a trunk with them before I make any decisions.
