How to see a voicemail

Call the service provider but if your provider is with ATT
this might be of help :
Resetting Voicemail Password

1. Reset Voicemail Password online at att.com.
2. You will receive a free text message confirming the voicemail password has been reset.
3. Press and hold the 1 to call the voicemail system from your wireless phone.
4. When prompted, enter your new secure 7- to 15-digit voicemail password, and then press the # key.
5. Follow the prompts to complete the voicemail password reset process.
6. You will now be able to receive and listen to voicemail messages.

example is att every company is different
Set up Basic Voicemail AT Wireless

The voicemail is on the computer at your carrier's office, not on your phone. Call ATT or Verizon (or whoever your carrier is) and ask them to reset your password - then log in, listen to voicemails and change your message from there. If the phone is old and no longer connected to a carrier, the messages are lost unless your new phone uses the same carrier (you should be able to log in with your new phone and listen to old messages if you did not delete them yet - even if they came in when you owned this old phone.

I would also suggest downloading the manual. I have my answering service thru att and I call a phone # assigned to me to check messages at any time.

It's not in the manual for the good reason that the AT&T 992 isn't an answering machine. If you want to record an outgoing voicemail greeting, you'll have to do it on the voicemail system, not on the phone.

The AT&T 992 isn't an answering machine. If you want to know how to record an outgoing voicemail greeting, you'll have to tell us the make and model of the voicemail system.

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.

Hi,

You can try reset your phone, Turn off the phone, remove the AC adapter, press and hold the page/call button that is on the phone and plug back your Ac adapter, see if this fix the problem.

If you're talking about the answering machine greeting in the base unit, detailed instructions are here: http://www.uniden.com/pdf/DECT1580om.pdf

If you're talking about the voicemail system provided by your local telephone company, each will be different, but my ATT UVerse voicemail is controlled at http://www.att.com/uversecentral and then click My Account, My Services, U-verse Voice Home Page. Hopefully ATT doesn't shuffle around the menus by the time you read this. This is correct as of Dec 2010.

I would check with your cellular provider to make sure that they kept your voicemail when you purchased the new phone.
