I have been reading and attempting to understand this issue of VoIP. I have talked some out of using any VoIP service because of all the problem expressed. Well it finally happened. I have a customer that decided to get his phone service thru Comcast Cable network. He indicated that he was told it will work with an alarm system. The panel is a NX-8E. So I asked him "is this VoIP??" He says what is that??? So I says Voice over IP. "No" he says, "I don't think it is." I says well we need to test to make sure that it can really work. So we test.................. six times total we send signals. And it worked every time.
So here is my question. What is Comcast doing or did we just get lucky?? Any all thoughts here would be very much appreciated.
