Hi paulcarter55,
Thanks for posting on our community forums. Sorry to hear that you currently have no dial time on your landline, even after a reboot of the router.
Can we ask if you're telephone symbol is flashing red on the front of your router? Have you tried unplugging the landline cord from the router and re-seating this?
Can you please the above and come back to us, if the no dial tone still continues.
Kind regards Jodi.
