What should I do if I have no dial tone on one or all of my telephones?

No Dial Tone on ONE phone:

It is likely that the problem is caused by telephone equipment failure. Disconnect the non-working phone and plug it into a wall jack that has a working telephone connected. If you still do not hear a dial tone after moving the phone, the problem is most likely in the telephone you unplugged. If you've elected the AT&T Telephone Protection Plan, AT&T will repair your telephone at no charge.

If you hear dial tone after moving the telephone it means that the problem is most likely in your jack or wiring to the jack. If you choose to contact AT&T please mention that you have already tried an "unplug" test. And, if you have the AT&T Inside Wire Maintenance Plan, AT&T will repair your inside wiring and wall jacks at no additional charge. If you do not currently subscribe to this plan you may incur a service charge for repairs performed by a qualified AT&T technician.

No Dial Tone on ALL phones:

These instructions may help you fix the problem yourself. Following these instructions first can help you better understand where the source of your trouble resides.
