Re: Can not connect to another line

If none of the buttons will work on your phone either the printed circuit board in the phone is bad or one of the buttons on the phone is partially pressed down. Try removing the clear plastic cover on the front of the phone and see if it will dial out ok then. If it will you should be able to replace the cover and use the phone with no problem.

No Dail tone on Line 2. We have 4 lines in total. Today when we pick up line 2, it's open and there is no dial tone. How do we fix this?

It's a good bet that the line is dead before it comes into the building. Call your service provider and start a trouble ticket.

I cannot dail out on my line . I get a dial tone but cannot dail out.

Have you changed anything, or did this just happen?

Usually this happens when the lines get reversed on a jack.

It is possible that the lines were reversed coming into the house, or at an individual jack.

If you have more than one jack in the house, try the phone in another jack, and see if it works.

No dail tone --but phone line is connected


If the dial tone is not heard check the volume. It may have accidentally been muted or turned down.

Is the phone line plugged into a surge protector? The surge protector may have stopped working or blown a surge, a sudden burst of electricity, which may have caused the dial tone in your cordless phone to go. Unplug the phone line from the surge protector then plug it back in and see if you get a dial tone? It could be that the phone line plugged into the surge was loose.

Try a different phone plug, outlet.

If the other phones on that line work OK, disconnect all the phones connected to the line, leave them all disconnected for 3 minutes, and then connect one at a time.

If still a problem and the other phones on that line work OK, give this a try:

Unplug the battery in the handset, unplug the phone line from the base and unplug the electricity from the base. Leave everything unplugged for an hour or two. That way you can get more of an idea of whether your phone will work. After an hour or two, plug in everything.

Hope this helps.

Need to change phone back to tone dialing

Here's what the manual says: Changing the Dial Mode (Tone or Pulse Dialing) (HS1 only) Your phone can communicate with the telephone network in two different ways: tone dialing or pulse dialing. These days, most phone networks use a method called tone dialing, so your phone comes programmed for tone dialing. If your phone company uses pulse dialing, you need to change your phone's dial mode. If you don't get a dial tone or can't connect to the telephone network, follow the steps below to modify your phone?s settings: With the phone in standby, press and hold [cid/menu]. Press [vol/ / ] to move the pointer to select DIAL. Press [select/channel] to set the phone to pulse dialing. Press [end]. Return the handset to the base. The handset communicates the new setting to the base, and the base activates the setting on any other handsets. Hope this helps out. K

Check to see that you have dial tone from the phone company by using a standard non cordless phone. if you have dial tone then check the cordless phone and make sure you plug into the correct port and ensure that you have the power plugged into the wall. Also, use the same cord from the standard phone that is connected from the phone to the wall to ensure that your line cord is not bad.

Samsung 816 power outage dailing an outside line

First thing you should verify a dial tone on the fax machine. (use any analog phone)
If you have dial tone, press 9 and then a number
Second is it conected through tel. system? (did it have an internal extension) and there is no dial tone then your analog port may be fried. Call your telephone vendor. He should be able to help you.
You can purchase a manual for about 10 dollars
Email your system model number to sales at for further instructions

Our company has a Panasonic kx-t7731 main line has no dail tone.

On that phone, press PROGRAM the button and dial 01 STORE.

Press program again to exit programming.

It's not likely you'll be needing the Group Log In/Out button.
