Cannot connect the phone to line

I bought this phone in US and I took it at home in Europe. Here the phone doesn?t want to connect properly to the phone line. It receives sounds perfectly including the Caller ID but doesn?t transmit anything, not even the dial beeps needed to dial the number. Any solution please?

SOURCE: Caller ID does not work


What I did was UNPLUG the base's power unit from the wall... waiting about one minute, and plugged it back in.  That caused it to "reboot" the entire system, and the CID now shows itself.

SOURCE: caller id function does not work

I had the same problem
I learnt that in India DTMF is used while in US it is FSK for Caller ID`s.
Get a EX220 converter and put it in between your Tel and system
It works

SOURCE: I can't dial out from my handsets

Here is something to try:

Disconnect or unplug the power supply (the small black box that is plugged into the wall outlet) wait for 30 seconds and then plug it in again. Sometimes the power supply needs to reset itself. It worked for me.

SOURCE: cannot answer phone when it rings

when you lift the handset from the cradle try pressing the line number button on the handset or answer button on the handset.

SOURCE: phone numbers not showing on caller id LED screen.

disassemble the handset (if you can figure out how to get it open). Flip the LCD screen over so that you can get to the end of the wire ribbon. You want the end that is connected to the phone, not the LCD screen. Carefully use a heat gun or hair dryer to heat the cable being careful not to melt it. Your goal is to melt the glue that connects the tiny wires to the electrodes. When glue is melted use a pencil eraser to press the wires so that they make contact again. Let it cool and try it out. It should work well after that. Put your phone back together.

My phone doesn't have dial tone. Each time I dial a number and try to call,it wont work. I call my phone but it wont ring. I need help on this. What happen to the phone? Or what should I do?

If you have another phone connect it to the wall outlet to see if you get a dial tone. This will indicate if your base unit is faulty.
Check the power adapter to the base unit, make sure it is getting mains power.
If the base unit has dual phone lines and if line 1 is only connected and the line 2 has beed selected then you cannot get a dial tone. In the chase press the line 1 to get a dial tone.
If your base unit has only one line then check the phone line at the wall socket make sure it is plugged in tight, also check the the connection at the base unit.
If this does not work then ring the phone company and get the to test your phone line, you may have a faulty line to your home.

Check the cord from the phone to the handset - wiggle both ends to see if you get more noise. Could be a bad connection or bad cord.

I just installed a replacement At&t EP 5962 2 line, answering answering device telephone. Line 2 does not get a dial tone. I installed it into proper / same as before outlets and both lines light...

There may be damage to the wiring of line 2 (either in the building or on the phone). Are both lines wired to one jack or are they separate? Do you have any other jacks that have line 2 connected (preferably as single line jack) in the building?

I like to use an old single line corded phone that does not use a power adapter. (As long as the EP5962 corded base will work without power (POTS), it might work for the tests below. You might want a simpler phone to carry around.)

If the lines have separate jacks, try switching line 1 and line 2. (Connect your Line 2 jack to the Line 1 input on the phone and vice versa.) If line 2 doesn't give a dial tone when connected to line 1, see the next set of tests. Otherwise, contact AT&T if the phone is under warranty. These phones are not meant to be user-serviced. Alternatively, plug in a different phone to the line 2 jack to test for dial tone.

Next move to another jack with line 2. Check if you have dial tone at that point. (If you do, you know the problem is at the first jack or the wiring to the jack.)

If there is no dial tone at the next jack or you do not have another jack for the line, find where your telephone service comes in. Open the service box and determine the type of connections in the box. If you are lucky, you will find RJ-11 jacks for the incoming service. Plug in your test phone and check for dial tone. If you have no dial tone or can't check the service, then contact your telephone company. They will test your line and fix it free if the probIem is outside.

If you have a dial tone, then it's 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. has clear pictures of the wire color to pin pattern.

You may want a professional to check the wires inside the walls. Your phone company will fix problems for a fee.

Damaged DSL filters on one line could be the cause. Similarly certain animals may have chewed on the specific wires somewhere in the line.

I hope this helps.

We have just bought a Vista 390 and are not able to get the hands free microphone to work. the speaker appears to work but we are unable to talk .

It took me some time, but I found out from the manufacturer Aastra (1-800-288-1683), that the issue with the Vista 390 hands free speaker is related to your internet connection. If your internet is connected to your phone line, you will need to put at least 2 DSL filters on your Vista phone line. I had to put 3 before I could use the speaker phone feature properly. 1 filter by the wall, one by the phone and had to connect a 3rd one before the two-way speaker feature would work properly. Your phone service provider should be able to provide you with these DSL filters...

LG VX8700 - No sound coming from speaker

Sounds just like the problem I had. I took the phone apart and removed the internal speaker. Tried the contacts with another speaker from another phone...and it worked.This leads me to believe that the internal speaker has failed. I am now on the hunt to get a replacement speaker.
