I have a question about Comcast Digital Voice service and other similar VOIP services such as Vonage that I can't seem to find the answer to anywhere.
What I want to know is----does it work in such a way that I have to plug a phone I want to work into the adapter they provide in order for it to get a signal? Meaning only the phones physically connected to the adapter will work?
Or does it somehow transform my existing phone jacks throughout the house into VOIP jacks so that any phone that is plugged into a normal phone jack will work with the VOIP service?
Thank you,
mike.
