Failed403 no dial tone at phone, yellow LED indicators

The pulsing dial tone usually indicates a message on the service provider's server, not on your phone. Contact your provider to find the procedure to access these messages.

It's stutter dialtone and indicates you have voicemail. Once you clear your voicemail the stutter tone will go away. You may also have a visual indicator that you have voicemail like a light or icon on the display.

Resetting the voice message waiting indicator
When you receive a new voice mail message, the new message LED on the top of the handset flashes. In the event your message waiting light gets out of sync with your phone company's
voice messaging system, you can manually reset it back to the "No messages waiting" state.
1. Press and hold FiND on the base for five seconds.
Note: The handsets connected to the base will start to beep, however, keep pressing for five seconds.
2. A beep sounds and the message alert tone is reset.
Changing the dial mode
Your phone can communicate with the telephone network in two different ways: tone dialing or pulse dialing. These days, most base networks use a method called tone dialing, so your phone comes programmed for tone dialing. If your phone company uses pulse dialing, you will need to change your phone's dial mode. If you don't get a dial tone or can't connect to the telephone network, please follow the steps below to modify your phone's settings:
1. Press MENU/SELECT.
2. Select the Global Setup menu, and then the Dial Mode submenu.
3. Scroll to highlight Pulse.
4. Press MENU/SELECT. You will hear a confirmation tone.
If you ever need to change the dial mode back to tone dialing, follow the same procedure, but select Tone in step 3.

Finally for future ease of use, here is a link to the user manual were I copied the above information from:

Programming Speed Dial Numbers
The handset must be OFF.
1. Press PROG. The IN USE LED will blink to indicate that you are in the programming mode.
2. Press the number of the memory location you wish to store the number in (0-9).
3. Using the dial pad, dial the number you want to store. The number can be up to 16 digits long. The number can be entered manually or by using REDIAL.
4. Press MEM to store the phone number
to the key you selected.

The phone now exits PROG mode and emits a tone.


Speed Number Dialing
1. Press PHONE to get a dial tone.
2. Press MEM and the memory location number key (0-9). For example, to dial the number you assigned to key '8', you would press PHONE, MEM, 8

Check that you have power (eg. Led indicator is on) to your Base station.

If you have power to the base station and you still do not have a dial tone, plug in a non-cordless handset to the phone socket and see if you have a dial tone on yor non-cordless handset, then you have a faulty base station.

Hope it helps and good luck! let me know how you go!

The VMWI led will stay lit if you have voice mail service from your telephone service provider. A lot of providers will also give a broken or stutter dial tone when you first go off hook as an indication of messages waiting. If you hear a stutter dial tone when you first go off hook, you will need to contact your telephone service provider. If not, you can try a simple reset on the base unit, just unplug it from teh AC adapter for about 5 minutes and then plug it back in.

You have a feature active on your phone it's more than likely a call forward feature which would redirect you calls. The broken dial tone or stutter dial tone is an indicator a feature is active. Contact you system admin for the clear all feature code and the clear all call forwarding codes.

When phone is on standby press memory-the talk led lite should flash. enter the phone # you want to store then push memeory again. Select the speed dial # you'd like to use for this phone # (0-9) then you should here a tone indicating it was successful. Let me know if this works for you-it should!!

I have two older (2002) model cordless Uniden phones that require the handsets to return to their original factory bases. If they have rested on another Uniden base, even of the same model, there is no dialup tone. Replace to the original base and you should be back in service.
