I found another phone system that is not compatible with Comcast caller ID! Bizfon. Yes well that's not a real phone system, hahaha. Yes Comcast's XMPP explanation to me doesn't jive. The Comcast rep was pretty certain that he knew the technology better than any veteran phone installer. Ha that's a joke.
I don't know much but I do know not question what has always worked in the past. Then a new guy comes into town with a new technology and expects everyone to dance the same tune.
