Question about Phones

Line in Use on displays

3 times now our phones have displayed line in use when they aren't. We can't get a dial tone even on our corded phone. After a period of time, they have started working on their own. I've tried disconnecting all of them and their batteries too. It doesn't make a difference. Is this a phone or a phone service problem?
Thanks

Sounds like there is continuity on your wiring to your phone jacks. Continuity means that somewhere on your wiring two wires are touching and shorting out your signal. Call your service provider be it verizon or at&t and have them test your jacks back to the d-mark.

SOURCE: No dial tone, just buzzing noise - should be 2 line phone, 1 jack

What you need is a dsl filter since you are working off a splitter. You can usually get these for free from your phone company.

SOURCE: telephone (land line) has no dial tone-- after a big rain storm

Let's make this official, then. Problem has to be in the modem or some piece of the cable or phone company outside equipment. You should get them back out for a closer look.

If this solution has been helpful, please take a moment to rate it. Thanks for asking here!

Meridian M3820 - why is display not working


Try another 4 wire phone cord from the wall jack to the phone it is possible that you have a bad cord. These phones will only work with a Meridian System .2 wires are line ,the other 2 wires are power to the phone. If you have another phone try plugging it into the same wall jack to check the jack/line itself. Anything else would be a defective phone/ lcd ( note you can have dial tone without display, but the unit will only access one line.

Phone not working


Hi Pam,
Try these..1...remove your telephone line from base unit and fix it into a working land phone and check whether is it having normal dial tone.If it's having engage tone(beep beep...)remove paralleled phones and re connect to cordless base unit.
2.If line is ok (normal dial tone with full volume) & still display indicates line is busy, your main base unit must be having faulty components inside.Commonly these defects happen in thundering or surges through telephone lines.You have to take full set to a repair shop.

Cannot get the pulse tone off the line and that prevents from voicemail access and call forwarding HELP!


In guessing that since your lines have defaulted to pulse dialing that you have an older Nortel system such as an 8x24 or a 6x16 system. That being said you'll need to program touch tone dialing on each line.

Programming is done on M7310, M7324 and T7316 sets.
To set up ringing you need to enter programming by pressing the feature key followed by **266344.When prompted to enter the password enter 266344.
the display says A. Configuration
4 top line/feature keys are now used for programming
Press the show key (top right arrow)
the display will say1. trunk/line data
Press the show key (top right arrow) .
the display will say line 001.
Press the show key (top right arrow)
the display trunk data
press the show key (top right arrow) Press the next key 7 times(bottom right arrow) .
The display should say Dial mode: pulse.
Press the Change soft key (below the display).
the display should now say tone. press the heading key (top left arrow) to get back to "trunk/line data" repeat the steps for the remainder of your active lines
press Rls when finished

Phone has a dial tone but will not dial


I would first verify that the line is good. Take a known good corded phone. YES corded phone !!! and try dialing with it and make sure it dials on the line every time. Also make sure that the Pulse/Tone setting is set for your service( there is still a few area without Touch Tone belive it or not)

Once you verify that the line is ok check each phone and take the defective ones back to where you bought them.

Phone cords


With the lines lit on the phone, it's indicating an off-hook condition or no battery from the line. Check the lines for dial tone at the demarc to determine if it's phone company problem. Thank you. Jer

Have ONE phone - ONE base station - still says "PLEASE REGISTER"


With the 6.0 gig set, the phones in the box are already registered. The manual tells us how to de-register and register. You might want to consult that part of the manual.
