No dial tone phone jack tested ok phone rings incoming call when you pic up nobody. changed battery still no dial tone or conection on incoming call

open line if have more than one phone plugged into a jack unplug one at a time and check dial tone if no change have phone company check incoming line

How many handsets do you have on this system? Just the one for the base unit?

Some of my telephones will read "Line In Use" when the phone doesn't detect a dial tone. I like to use an old wired telephone to check whether the problem is with the cordless phone base or the phone line wiring.

First plug in the test phone and check for a dial tone. If there is no dial tone, try a different RJ-11 cable between the phone and the jack. If there is still no dial tone, use the test phone at another jack and check for a dial tone. If you have two jacks with no dial tone, find your incoming telephone service box. If you have a relatively new phone service installation, the service box will have RJ-11 jacks. Plug your test phone into the jack and check for a dial tone. If there is still no dial tone, contact your telephone company. They will repair an outside wiring problem for free. If the service box doesn't have an RJ-11 jack, you'll need to ask your telephone company to test the phone line for you.

If there is a dial tone at another jack or at the service box, you have an inside wiring problem. You can check for loose or broken wires inside of the jack. Most use either screw terminals or a punch-down design. For the screw terminals, strip another section of the unbroken part of the wire, if needed. Secure the wire under the screw. For the punch-down terminal, take off the cover. Then you'll need a tool that is available in most hardware stores in the electrical wiring section. Do not strip the wire; just place it over the correct place in the terminal and push it into the contacts with the tool. Trim off any excess wire with a small pair of small wire cutting pliers, if the excess wire is blocking the cover from fitting back onto the terminal. http://www.lanshack.com/wire_phone_jack.aspx has a good diagram of the wire color and pin assignments. If the wiring is okay at the jack, you'll need to check the rest of the wiring for problems. Since the broken wire might be inside the wall, you may want to have a professional check it out. Your telephone provider's technicians can do this for a fee. If you have a DSL computer line, you should check the DSL filter. If the filter is inside at the jack, you'll need to replace the filter. If it is out at the service box, your telephone company will do the replacement.

If there is a dial tone at the jack with the test phone, check the purchase date on the L401 system. If it is under warranty (1 year usually), contact Motorola. Otherwise, replace your Motorola phone system. It's generally not worth the minimum repair and shipping costs.

I hope this helps.

(I've had dial tone issues after lightning strikes (the DSL filter was damaged), mice eating wires (buried phone line) and due to county road crew/contractors who dug too close to the wire. The first two problems required phone calls to get a technician to fix the outside line. The last one gets fixed by the contractors/phone company as soon as they can.)

notify phone provider to check and test lines

No dial tone on telephone set? could mean alot of things. Phone went bad, jack is bad(test in different jack or from a network interface, either inside or outside. depending what your dwelling is)
Just to point out a fact, when dial from your mobile to that number that has no dialtone, that ringing sound you hear is from the central office that is putting out that ringing, it has nothing to do with the phone you're trying to ring to. You would hear the ringing sound, even if all your phones were unplugged from every jack in your dwelling.

Take your incoming phone line and plug it into the place that says "line" on your fax machine. Plug another phone cord into where it says "phone" and connect this to your telephone. Test to make sure you have chosen the right places by dialing a phone number to fax to and listen for the dial tone. If you get a dial tone, then you have set it up correctly.

On the fax machine look for the button that says "menu". Push it and use the up and down arrows to navigate the options on the display. Look for fax set up and press "ok" or "enter" on the fax machines keyboard to access this area. Look for "number of rings" and change the fax machine to a number of rings that is less then your voice mail box if you have one. Then close and save your choices.

Have someone send a test fax by dialing your phone number for the line connected to the machine. The fax machine will pick up on the number of rings set and automatically begin receiving and printing a copy of your incoming fax.

You cannot use magic jack.

You can also choose to manually answer an incoming fax if you see that your display on the fax machine says "ringing" or incoming" you can push the "start" button and this will start receiving your incoming fax.

This can be a problem with your handset.
Have you tried a different phone in that same jack?

did u try removing the battery and reinserting after 2 min..

and if already tried,

then try dialing from oter phones, or check the assign tone in ur phone contact from which ur testing to be assigned with some ring tone...

I disconnected the RadioShack phone/answering machine and plugged in an old phone. At first I didn't get a dial tone, but in a minute or so, I did get one. I doublechecked the connection with the incoming phone jack. (I had checked this before, but didn't see anything wrong.) Again, I didn't see anything wrong, but maybe that did it. Also, when I disconnected the RadioShack from the incoming phone jack, I disconnected from my computer (I used to have dial-up connection).

Don't know which of my actions worked, but now I have dial tone on Radio Shack.
Hoooooooray!!!!
