Panasonic cordless handsets all say line in use

All my handsets say Line in Use even though nobody is on the phone, no fax is coming through and no phones are off the hook.

Have Panasonic KX-TGA541S and Panasonic KX-TGA560M and have never had this problem before.

    I'm having the same problem with my Panasonic phone. I was at this site and went to take the batteries out and try the solution, and the phone was working . It's been saying "line in use" all day. Now the phone has a strange buzz on it, but it's working.

    It doesn't seem like it could be the "memory stuck" thing because it comes and goes? Oh my.

    I had the same thing happen this morning - no phones off hook. I will try the solution listed here. I hope it works. Panasonic cordless.

    All my Panasonic handsets (4) displayed "line in use" and this made it impossible to call out and incoming calls went to voice mail. As it turned out My problem was not with my Panasonic system but with a separate phone I had attached to my phone line. This other phone was also a digital phone and it also had some additional features. It was the culprit causing the problem. Removed it from my phone line and my Line In Use problem went away. I suggest removing everything from your phone line but your cordless phone system first to eliminate something else that might be causing your problem.

I had the same problem. Something makes the phone's memory get "stuck."  Take the battery out of the phone for a minute and then put it back. Then unplug the phone and plug in again. You need to do this with all extensions. The problem goes away.

    1-10-19 -- we have a set of four Panasonic phones. We lost power during a storm last night, and this morning we realized we had power again, but the phones did not work, incoming or outgoing. The message on each phone was "Line 1 in use" or something similar. After ripping my hair out, I found meb219's solution. It took patience and time to follow those instructions for each phone, but it absolutely worked. Thank you, I believe!

Better late than never. I had the same problem with Panasonic phone and Nettalk service. The problem with the "INUSE" was fixed by removing the phone line connection to my DirectTV DVRs. Once I did that, the phone immediately was ready for use.

Return to the manufacturer for replacement. I've spent hours on this and have had my line tested. It's a base station fault.

I had this problem as well. Take the battery out of the phone for a minute or two and then put it back in. Unplug the the phone (jack and power supply) including all extensions, then plug them in again. This should work. I worked for me.

    We were having this problem at work. I tried this suggestion and it did seem to work. But then the same problem came back the next day. Not sure what to do next. Maybe replace the batteries? (although the extensions have been working fine until this problem, and they have not lost battery power as far as I can tell)

This has happen to me twice. The first time a dog had chewed the extension lead for the base phone. Replaced the lead and it worked.The second time I thought it was the same problem with the lead that went through a door and the door had damaged the lead, so replaced the lead, but it didn't fix it. Got another phone and tested the upstairs jacks and there was no dial tone so called Telecom to fix. The weird thing was I still had internet and email access so I didn't think it was a problem at their end. Seems there was a fault at the exchange and our phones are all working again now.

SIMPLE FIX clears "In Use" from your Panasonic handsets: On the back side of your MAIN BASE SET ONLY, DISCONNECT both the phone & power lines and RECONNECT.

(This cleared my Panasonic KX-TX5100 base & KX-TGA510M handsets after a thunder storm.)

SOURCE: out of range shows on main handset of cordless phone

Unplug the battery. Hold down The * (star) and the #(hash) keys simultaneously. Re-connect the battery, phone will beep and screen will be blank. Press the voicemail (righthand silver key under the lcd screen). As above EEPROM/RAM message will appear. Place handset on base and your problem is solved.

SOURCE: No dial tone on Uniden Dect 6.0 land line and portable phone

We've had the same problem with our new Uniden phone. Sounds like someone's on the other line - no dial tone and answering machine doesn't work. The telephone line works though because we plugged our old phone in and it works fine. Any solutions anyone?

SOURCE: Error message CHECK TEL LINE

This sort of issue requires you to check if the base or the phone line has a problem.

I prefer to use an old corded phone for testing. I also get a new RJ-11 cable. Unplug your phone base from the jack and check for dial tone when you plug in your test phone.

If you get a dial tone on the test phone, try the new cable with your cordless phone. If you still get that message, then the phone has failed. If it is under warranty, contact the manufacturer for repairs. If it is out of warranty, then determine if it is worth fixing or replacing. These phones are not designed to be fixed by the end user.

If you do not have a dial tone, take your test phone to another jack on the phone line. Check if there is a dial tone at that point. If there is a dial tone, the problem is at the first jack or the phone line to the jack.

If you still do not have a dial tone at the second jack, find where your telephone service comes in. Open the box and determine the type of connection used. If you are lucky, it will have RJ-11 connections. Plug your test phone into the jack and check for a dial tone. If you do not have a dial tone at this point, call your telephone company. They will fix the problem for free. If you find that the connection is not an RJ-11 type, call the phone company and have them test the line and repair it if needed.

If you have a dial tone at the service box, then you have an inside wiring problem. Inspect the visible wires for damage. Open the faceplates for the jacks and check for loose wires. There are two types of connectors. Screw type connectors need the wire stripped back a little then wrap around the screw and tighten. The other type is a punchdown jack. To repair a loose wire in this, you will need a punchdown tool. These are often available in hardware/home improvement stores in the wiring section. http://www.lanshack.com/wire_phone_jack.aspx has clear pictures of the wire color to pin pattern.

You may want a professional to check the wires inside the walls. Your telephone provider will do this for a fee.

I hope this helps.

Do two handsets plug up to telephone line? If so how?


The main unit with answer machine has an inlet line where the phone line from the wall plugs into,which is located in the back of unit along with where the power cord gets attached. The second handset should have a stand/charger unit that should just plug into an outlet only to charge it. The two handsets run off the main answering machine/ unit. So as long as that is plugged in you should be able to use both handsets, because they both operate on the same frequency wave. Hope this helps you.

Phone shows line in use even though both handsets are off.


unplug the phone line to the wall if it sill says "line in use" there is a short on your phone and you will need a new one. If not there is a short somewhere on your line. Call your phone company to repair your line. Note the phone company will charge you for repairs inside your hose.

These phones are digital proprietary telephones which means that they only work on panasonic telephone systems and not on normal analog lines. If you have a panasonic system the correct way is to plug the line into the " To Main Unit ", the handset into " Handset/Headset" and a normal analog phone into " To Tel ". If the wiring on the line jack was not done digitally the phone will also not work

Sounds like your telephone line is dead. Call your service provider to determine if its a problem on their end.

I have the kx-tg 4500 4 line base unit phone. Line one flashes but does not ring or display caller. The other lines work fine. The handsets show no activity ie they don't even flash if a call comes in on...


I had the same problem once, turned off the base unit from power cord and the phone line and all connected handset units, then turned it back on & it worked.

Panasonic KX-FM220 fax machine does have a dial tone


I would double check your phone cord. There is usually 2 jacks in the back of the fax machine. 1 is for Line, and 1 is for phone.
Your phone cord should be hooked up in the LINE jack that goes to the wall.
I would also double check your phone cord on another phone to make sure the cord is good.
If you look at the clear connector that you plug into your wall and fax machine, does it have 4 copper/gold color wires contacts imbedded in the clear plastic connector?

Another thing to try, if you fax machine has a Line and a Phone connector, try plugging in a phone in the PHONE connector. Then hook up another phone cord going from the LINE to the WALL jack.
If you get a dial tone on your Phone, then you know you have it connected correctly. If no dial tone, then I would go back to the phone cord.
check those things and get back to me and I will see if I can help you with more suggestions.
Good luck.
Mac =)
