Comcast users: How do you hook up your phone line with this modem? The modem I rent from Comcast has a phone line input that I have to use for my phones in my house to work. Judging from the pics, this modem doesn't seem to have that input, so how do you use your home phones? Thanks.
you don't with this modem. ask comcast what they require. they told me i must continue to rent their modem. i most likely will cancel comcast voice, as i just cancelled their xfinity and went with directv.
You just need to add a router. Then connect your voip adapter to the router. Plug phone into Voip adapter and you have phone service. All of this assuming you have a Vonage, Ooma, or other phone service adapter
