[Electronics-Talk] Modern Landline Phone Service

[Gerald Levy]

Here's the problem. You may still have low voltage current flowing 
through the phone lines in your home.  This current has to be shut off 
in order to use the existing jacks with Comcast VOIP.  Most likely, 
Comcast has been prohibited from accessing the main junction box to cut 
off the current because it is probably the property of the big bad arch 
rival phone company, either Verizon, AT&T or some other regional 
carrier.  The cable companies hate the phone companies and vice versa, 
andare seldom willing to cooperate with each other for the customers' 
benefit.
