M7310 Non-Stop Dial Tone

Unfortunately, you'll need to do some work to find the issue with your telephone. Currently, it isn't receiving a dial tone. First, for a cordless phone system, check if the base has power. (Make sure that the power adapter plugged into the base and the adapter is warm. Try another outlet if the adapter is cool.) Check that all handsets/phones are off/on hook.

Next try changing the RJ-11 phone cord between the base and the jack. (I've seen someone plug in a handset cord between a telephone and the wall jack.) For the rest of my trouble-shooting, I like to use an old-fashioned corded phone. These don't require power to test the POTS line at other locations. First, try plugging the RJ-11 cord into the test phone and lifting the handset. If it has a dial tone, then the problem is with the original phone. (If you had no dial tone with either phone and you have DSL, try replacing the DSL filter if it is inside. If the filter is in the service box, contact the telephone company.)

Next, take your test phone to another phone jack for the same number. If you have a dial tone here, then the first jack has a wiring problem. This could be in the jack or the wiring to the jack from the incoming line. The jack is easier to check. Take off the face plate and look for loose wires. The jacks come in two forms: keystone and screw terminal. For the first, do not strip the conductors and secure them with a punch-down tool. (The tool is available at most hardware stores in the electrical section.) Use https://www.lanshack.com/wire_phone_jack.aspx for the correct pin locations. For the other type of jack, you need to strip the conductor before securing it under the appropriate screw.

If you did not have a dial tone at the second jack, find the incoming service box. Open the box and check if there are RJ-11 jacks inside. If there are, plug in the test phone and check for a dial tone. If there is no dial tone or the service connections aren't RJ-11, contact your phone service provider. They can test the line and should repair outside problems for free. Outside problems can be caused by rodents chewing on the wires, a careless contractor digging or other issues. If you recently had a service call, check for an obvious loose wire. I once found that three out of four lines were plugged in after the service upgrade. After locating the misplaced wire behind the siding, I just plugged it in to solve the issue. The telephone company technicians can also fix inside wiring issues. However, there will be a charge for that.

If your cordless phone has an option for pairing with a cell phone, make sure that your phone has signal. Bring the phone close to the base and that you use the correct line to dial using the cell service.

I hope this helps.

(Copper wiring is most at risk from animal damage. Fiber Optic phone service problems can include a faulty modem in the service box. The symptoms of that can start with intermittent loss of telephone and internet service.)

Check your button programming using Feature *0 to see if the lines are programmed to your phone.

Call a tech in that handles the system programming to check the line port if ok and/or call your carrier to report the line as being dead.

You could plug your non-cordless phone into suspicious phone jack to see if you have dial tone-if you dont have dial tone, the line maynot be connected and you should open the jack to see if there is more than 1 cable attached. If there is more than 1 cable attached and you dont have dial tone at other end of cable the cable might be cut or shorted somewhere inbetween. You can test continuity by tying 2 wires together and test with a multimeter on resistance to see if it is open circuit or maybe even short circuit. To test for short circuit, untie the cables and you should not get a reading. If you do have dial tone when you plug in non-cordless phone the distance might be to far for receiver to pick it up(ie..greater than 10 metres). I hope this has been helpful.

familirize with devices user manual whether has feature functions requested. Second, ascertain that device was least malfunctioning since acquired. normally, familirising with innovative devices makes expertise in functionality.

The office you bought them most likely had digital phone lines and you are using analog.

Its the problem from the system.

Go to the programming of Norstar by Feature **266344 and the password is 266344.
Go to line datd or line and make dialling made as Tone.
It will fix ur problem.

Even though the plug that plugs into the wall on an M-7310 looks like the same plug that the answering machine has, it's function is completely different. The information passed on the single pair of wires is enough to make a 24 button 10 button or 8 button system phone work, has no ringing voltage or dial tone for a single line device like your answering machine.

A Nortel system has ports that have that information, but most likely the answering machine was installed BEFORE the phone system lines, which means it only answered the first line.

Try plugging your answering machine into the EXACT location it was before.

Any standard phone should work, even phones made in 1800's should still work on a standard phone line.

I'm not sure what phone you have. The one listed in the question "M7310" is a business system phone and will ONLY work on the Nortel business phone system.

If you have standard home phones, my only suggestion (using the information supplied) is to check if the Tone/Pulse switch is set to tone... even though both should work.

Do you have phone service through a cable line?

I had the same problem. I went to each handset and pushed the talk button. After I got a dial tone, I pushed it again to stop the dial tone. The message went away.
