The voicemail doesnt want to turn on

Question edited for clarity.

This phone system has two features.

Answerphone system which records messages to the unit.
and
Voice Mail System which is an extended (often paid) service from your telephone provider.

Sometimes a glitch at the Telcom will remove your Voice Mail. You will need to phone their customer service number and ask why they stopped the service you previously enjoyed? They will be able to put it back in place.

Retrieve voicemail from telephone service Voicemail is a feature available from most telephone service providers. It may be included with your telephone service, or may be optional. Fees may apply.

Retrieve voicemail When you received a voicemail, the handset displays New voicemail and . To retrieve, you typically dial an access number provided by your telephone service provider, and then enter a security code. Contact your telephone service provider for instructions on how to configure the voicemail settings and listen to messages. NOTE After you have listened to all new voicemail messages, the indicators on the handset turn off automatically.

Set your voicemail number You can save your access number on each handset for easy access to your voicemail. After you saved the voicemail number, you can press and hold to retrieve voicemail. Press MENU when the handset is not in use. Press or to choose Settings, and then press SELECT. Press or to choose Voicemail #, and then press SELECT. Use the dialing keys to enter the voicemail number (up to 30 digits). Press SELECT to save. You hear a confirmation tone. • 1. 2. 3. 4. 5. 33

Turn off the new voicemail indicators If you have retrieved your voicemail while away from home, and the handset still displays the new voicemail indicators, use this feature to turn off the indicators. NOTE This feature turns off the indicators only, it does not delete your voicemail messages. Press MENU when the handset is not in use. Press or to choose Settings, and then press SELECT. Press or to choose Clr voicemail, and then press SELECT. You hear a confirmation tone.

From the sound of it it I think its either: your mailbox is full or the feature has been turn off accidentally.

Vtech's support recommend the following (I've removed things like 'make sure its plugged in' and 'is your answering system is turned on' etc..)

1 Some answering systems have an announce only option, which plays your greeting but won't record messages. Make sure your system is set to record messages.

2 Your answering system's message capacity may be full. You must erase old messages to make room for new ones.

3 If you have voicemail service in addition to your answering system, your caller's message may be going into voicemail before your answering system picks up the call. Program your voicemail to pick up at least 2 rings after your answering system is set to answer the call.

The VTech CS6719-2 isn't an answering machine. To set the voicemail, please refer to the documentation for whatever voicemail/answering system you have on your phone line. If you need a manual, you may download a copy at http://cdn-media.vtechphones.com/media/p/document2/products/%7B4B5F2951-48EE-413C-9CAF-3F956892A909%7D/CS6719-2_UM_2.pdf

If you require further assistance, please reply to this post and specify the voicemail/answering system you have.

There seems to be two separate issues here.

Your phone will not take messages if it the answering system is turned off. See page 37 of the manual: http://www.vtechphones.com/support/general/manuals

You apparently have unheard messages on the voicemail system provided by your telephone company. This system records messages when someone calls while you're already on the phone. Please contact your telephone company for instructions on accessing their voicemail system.

You might want to check the ring count on both systems. If they're both set the same, it's possible the phone company's voicemail system is picking up calls before your answering machine.

The CS6719 doesn't have voicemail capability. It will interface with the voicemail system provided by your telephone company, if there is one.

On most VTech phones the voicemail indicator turns on when someone leaves a message on the voicemail system offered by your phone company. Many phone companies have such a system, which takes messages when your phone is busy. You'll have to contact your phone company for instructions on accessing their voicemail system.

Since you declined to specify the model of your VTech DECT 6.0 system, I can only direct you to enter it into the search box here in order to download the manual.

stay away from vtech phones....two clams and some toothpick cord does much better....vtech [cheap bastards plain and simple]

The CS5113 isn't an answering machine. However, it works with the voicemail system offered by your telephone company. Please contact them for instructions on accessing their voicemail system.

On the main base is a round silver button. At the bottom of the button says play. It this does not solve your problem you may have erased them or your volume is turned down so you can hear them.
