Hello, About 6 months ago, I kicked AT&T to the curb (yay!) and switched to a VoIP "landline". I've been using just one cordless base plugged into the VoIP adapter with 4 - 5 paired cordless handsets around the house. What I want to do is plug the VoIP adapter into my existing house phone wiring so all existing jacks work for the phone service. I "think" I need to splice a couple of wires together in the outside box where the AT&T service came in, but what exactly do I need to do? Thanks for any advice!

Not sure where to post this Comcast VoIP question. I want to move (or completely remove) the cable that Comcast ran in my basement for their phone services. It is a Cat5e cable run from a Comcast box on the outside of the house to the phone outlet nearest the modem on the first floor of the house. Can someone tell me what the purpose of this cable is? It is my understanding that if I were to open Comcast's box and the Phone Co's box, I would find the connection to the Phone Co's network disconnected and I would find Comcast had spliced the wires entering the house with their Cat5e cable. Am I correct that there is no connection at all between the Comcast cable and the Phone Co's network? If this is the case, can't I remove the wire and still have all the phone jacks in the house tied into the VoIP - back-fed by the modem's connection to the closest phone jack? If so, is there any advantage to the way the Comcast tech wired it or can I simply remove the wire? Can anyone tell me why he wired it this way? I also want to mention that there is a Network Interface Jack inside the house with a single Quad cable running from the Phone Co's box, and a phone line junction box - but presently, this is not connected to the phone lines - having been disconnected during a renovation after the Comcast install. Not sure if the presence of this set up would have caused the Comcast tech to run his cable all the way back to the Phone Co's box. Also, also - want to mention that the phone line wiring does not utilize "home runs" back to any single point, so this was not a consideration in running the Comcast cable. Thanks for any help you can give me!
