NO DIAL TONE - Motorola Mobility MA 357 Cordless Phone (56429)

Since you declined to specify the model of your VTech 5.8GHz phone, I can only suggest that you enter it into the search box here to download a copy of the manual. The manual will describe how to switch between pulse and tone dialing.

First be sure you have dial tone at the jack. Use a corded phone to do this with. If you do have dial tone then be sure you have ac at the outlet that the transformer is plugged in to. If there is no dial tone at the jack...go to your interface box outside and check for dial tone there....if none call the phone company. If you do have dial tone then you need to check your wires to the jack...or have the phone company do it for you. If you don't have ac at the outlet....check your breaker box or have an electrician check for you.

Either button mapping or no dial tone at the system cabinet. If your desplay sas CO1 and you have no dial tone, go to the sytsem cabinet ans swap the modular plugs for CO1 and CO2. If the No Dial Tone moves, "mus be sumpin wrong wit yo lines".

I would contact your phone provider. It could be a coinceidence that the dial tone stopped working.
DSL does not require dial tone to work.

Hello Mikenrgrsvll

This problem can be due to the software not handling a certain dial tone rather than a specific hardware fault. Around the world there is a variance in the signal quality of the dial tone which causes a report of no dial tone detection. Disable the dial tone detection to prevent the system from trying to detect a dial tone.
Disabling dial tone detection for modems:
Windows XP

1. Click Start
2. Select Control Panel
3. Click Switch to Classic View to change the control panel view
4. Click Phone and Modem Options
5. Select the Modem Tab
6. Select the installed modem (Example: Lucent Technologies Soft Modem AMR)
7. Click the Properties button
8. Select the Modem tab in the Properties window
9. Click Wait for dial tone before dialing to remove the check from the checkbox
10. Select the Advanced tab
11. Add X3 to the Extra initialization commands field in the Extra Settings box
12. Click OK twice
13. Select Switch to Category View to change back the control panel view
14. Close Control Panel

if this does not work trying re-installing modem drivers.

hope this helps, have a good day.

The problem was the main phone line not the phone itself

680 - There is no dial tone.

All versions of Windows are affected by this error.
No dial tone: There are many possible causes of a No Dial Tone Error.
First, try testing the modem's ability to detect dial tone and to dial by using HyperTerminal with the direct to COM port connect method - see Using HyperTerminal. If you give your modem an AT&FX1 command, and then a dial command, dial-tone detection will be disabled; if you still do not get dial tone, the modem may not be installed correctly (especially if it is a PCI or soft-modem); or the cable from the modem to the phone-line jack may be bad or installed in the wrong connector on the modem - try another line cord, and make sure you are plugged in to the LINE - not phone - jack on the modem. Plug a regular phone into the phone jack on the modem and make sure it has dial tone. The modem may also be defective. Many new modems come with an electronic circuit instead of the traditional electro-mechanical relay used to take the modem off-hook. Some of these designs are proving less reliable; often, they will be 'stuck' in the off-hook position, so unplugging, the plugging in the phone cord may give dial-tone. If this is the case, the modem needs repair or replacement.
If the modem will blind dial (x1), but not detect dial-tone otherwise, the problem is likely to be in the proper selection of the Country in Windows->ControlPanel->Telephony or in improper installation of the modem or lack of support for your country in the driver you are using. Check to see if there are updated drivers for your modem.
If the modem dials properly with detection (x3) in HyperTerminal, but does not detect dial tone when using DUNs, the problem may be DUNs (check for upgrade or re-install) or the proper setup and modem selection for the DUNs connectoid.
For Embarq telephone service customers, this error can indicate that you have a message waiting in your voicemail. Embarq changes the dial-tone sound to a "fast" busy signal when a new message is present in your voicemail box. This "fast" busy signal can confuse the modem into thinking there is no-dial tone present on the line.

The problem is possibly the keypad on the phone. Try another phone , preferrably a standard corded phone. If you still cannot break the dial tone, then the problem is with the telephone line (phone company)
