We have our own modem with voice (Netgear CM1150V). Recently activated our xfinity voice service, it is (finally) working. I say finally because there were glitches porting our number over. All is working now. When I plug a phone directly into the modem, that phone works. When I plug the modem directly into the wall jack to give all the phone jacks in the house dial tone- nothing. I've disconnected the old land line wires at the box on the outside of the house. I know all my internal phone wiring works (because it did the last day we had a land line). I'm at a loss of why this isn't working. I've asked on the Netgear website, no help there. So thought I'd try here as other likely have the same modem. Thanks in advance!

Do you have a phone cord connecting the CM1150V to a wall jack to energize the other jacks? If that doesn't work, as stated, you have a wiring problem somewhere.

It isn't realistic to expect Forum members to troubleshoot a wiring issue in your home. Comcast can't do it remotely either. You need someone on site with appropriate test equipment. Sorry to disappoint!
Do you happen to have a 3rd party alarm system connected to your phone wiring?
I have this same problem....but I get a busy signal on all the other jacks in the house. The phone that is plugged directly into the Gateway works fine.
When I use a splitter directly on the Gateway, i get the same behavior....dial tone on one phone and busy signal on the other....so I suspect its a Gateway problem and not a house network problem.
