Your voicemail system is down. You have to locate the card in the system usually all the way to the right in the cabinet, and reset it with the little black dip switch on the front of it. push it down and wait 5 minutes than push it back up and wait for a green lcd on the upper part of the card. Or you lost your voicemail system programming. You may need tech support or a tech to come out. ldtsnj.com

If you can't access the lines in order to hang them up, resetting the phone system will definitely release the lines.

You may need to set the main handset to synchronize with the base unit plugged into the telephone wall jack and assign special configuration numbers to the other handsets in order to properly identify each one within a specified location. One handset left in the turned on mode may make it impossible to place calls with the any of the other handsets. This will continue until either the battery dies or fails on the handset or the phone is switched off and replaced in its charger for charging again. Synchronize the main handset by pressing the MENU button on the handset, then pressing the down button IN order to select the number you wish to assign to that handset. Repeating this process if you have already done so will greatly decrease the level of errors experienced with panasonic phones MORE USEFUL INFORMATION FOR ALL YOUR ELECTRONICS When troubleshooting these units, there are always several variables to consider. First check to see what last occurred with the unit such as did the children play video games, did the electricity go out due to bad weather. You may see that there are many possibilities but let's focus on what occurred last to the unit. Once we determine what happened last, we may isolate the actual cause of the problem. The actual cause may be associated with projection issues, older versions (Picture tube), interference from devices located nearby, and even a radio turned on and located really close to your unit. This is normally known as electromagnetic interference to electronics and is very common with the error you have provided today. Please continue to look for anything EXTERNAL to the unit before looking at the internal components. I have been working on these a long time so feel free to follow up with me.

Hello, you didn't mention if the office phone was ringing and if it was which line was ringing when you tried to answer it. From the other information you provide, I suggest you do another test, make two calls in to your number at the same time to see if one of the calls comes in on line 1 or line 2. If the 3rd line is your main number and it is not working then making two calls in at the same time would force one of the two calls to roll to one of the other lines. This would verify that the 3rd line is not working and causing your trouble. If this is the case, the trouble could be from the service provider or in your phone switch or wiring. You could start by reporting the trouble to your service provider to see if they can test the line and determine if the trouble is in their equipment. Often, the service provider needs to have the customer premise equipment isolated(disconnected) from the circuit to conduct a valid test but if it is an open in the cicuit(line) the service provider may be able to "see" it without isolation from the customer equipment. If the service provider has to come on site to determine the trouble, you could incur a cost if they find that the trouble is caused by your equipment or wiring. At this point it may be best to call your phone system technician to determine where the trouble is depending on the cost of a service charge of your vendor compared to the service charge of your phone service provider.

Cant receive faxes. constant busy signal when dialing in.


Hi Janet
Try using a standard phone to call your Fax Line
Connect a phone to this Line to test for voice
Disconnect Fax Machine from Phone Line
Reset Fax machine
The Fax machine is supposed to respond to the right tones being sent down the voice line
If it is not responding & all else works then check your Fax settings for "Receiving"

All phones are plugged in and operating but i get a busy signal on all in talk mode


I assumed when you say all phones are operating means there's power and are charging.
1. There could be some phones that are loading the Tel line. Disconnect all phones and plug it one by one while checking the dial tone. If all phones gives busy tone, there coulb be a problem in the Trunk line or the Tel Company line.
2. There could be a short or resistance in the line. Check the connection in junction box between your house and the Tel Company cable.
3. If you have an analog Tel set, you can check the dial tone directly from Tel Company cable that comes in to your house.

I hope this helps.
Best Regards.

Why can't I rec or make calls?


What is happening when a call comes in are they getting a busy signal? If so your line is shorted out.. unplug all phones and see if caller hears a ring.. Then 1 at a time plug phones in. Check for a dial tone and press a digit, hang up and check and see if dial tone returns, repeat this on all phones, until you get to the phone that does not give you dial tone back after dialing a digit. That will be your bad phone... If the line was ring busy after all phones unplugged, call repair service..

My panasonic kx-tga431al has all of a sudden changed the dial tone. instead of the regular tone, it now has a tone that sounds like a busy signal... what do i do to fix this?


Hi,

Have you set up 'Call Divert' which returns a 'Broken Dial Tone'

Dial #21# if it is on a Single Line Telephone, or if fitted on a Business System check programme for 'Call Forward'

I cannot dial out.


The dial may be defective and when you dial it is putting out erronous tones. When the Phone Company heres digits that do not correspond to a legal phone number it will give you a error tone or busy tone. It could be the phone got put on pulse and the line won't recognize the pulses

Epson cx11 outgoing fax problems


This is not an issue with you unit, this is an issue with your phone line. get your service provider to check the line. also remove the line from your fax and put a standard phone on the end, try to make a call and see what happens. if the same result occures, there is an issue with the line and not the fax.

Outgoing fax never goes


Do you have the same problem with different numbers that you fax to? Are you usinga voip phone service? I use Vonage and have a lot of trouble with faxing. Call the number you are faxing to with a different phone and listen for a fax tone.
