My phone has no dial tone

Hi there, @user_mwjxla Thank you so much for reach out to us here! I'm very sorry for the trouble you are experiencing with your Xfinity Voice. If your Xfinity phone has no dial tone and displays "check phone line" even after resetting the modem, the issue could be related to your home wiring, a faulty phone jack, or a problem with the phone itself try plugging a different phone into the same jack, checking the phone line connections at the modem. If you are still having the same check phone line, please don't hesitate to reach back out so we can troubleshoot and get this issue addressed and resolved for you.-Richard
