I had Verizon for home phone and now I have Comcast for internet. I also have Comcast VoIP . Comcast VoIP rings all phones in my house and lets me keep my old number which is important since I have had it 40+ years. With you equipment can I keep my old phone number? It is important to me. If google voice will not let me keep my old phone number is there an alternate service that would which, would be of low cost, and that your equipment would work with (VoIP)?
