Have had Vonage for the last 3 years at my MD residence. Verizon is the land-line provider in my area and I had nothing but grief with them. ComCast is the internet connection

I disconnected Verizon Land-Lline at the outside connection box, and now use the internal house phone wiring for my extension phones.

Be sure to pay attention to how to rig it up for "911" calls!
