Display not showing new messages

This is a very standard wired Desk Phone with Caller ID. It does not have an Answerphone. Your Message Waiting is with your Telco Telephone Service Provider. Phone then and ask the procedure for checking your messages.

I doubt this basic phone has Call Forwarding UNLESS is is part of an office system with an Exchange Control Box. As a home phone bought from a secondhand shop, it is very basic.

Question edited for clarity.
Question moved from Cellphone to Lands Phone.

This is a very basic phone and has no Voicemail facility. If your phone company has that facility as an additional service, you phone them, request it, agree to pay the fee if there is one. They will send you details on how to access it on their servers, how to create your message and how to access it. It is also in this link if you have already paid.

This phone has no Message Waiting Light either. It has Call Waiting, but that is not Message Waiting.

Hi

Thanks for using FixYa. I think you have stored more than 100 Caller ID messages and hence the caller ID is not showing on Uniden Tru8888. In the following cases the caller ID will not be shown-

If you answer a call before the Caller ID message is received (for example, before the second ring), the Caller ID message will not appear.

When the call is received via a telephone company that does not offer Caller ID service, the caller’s phone number and name does not appear. (This includes some international calls.)

When the call is via a private branch exchange (PBX), the caller's phone number and name may not appear.

You may receive any one of the following messages:

When a private name is received; Private Name
When a private number is received; Private Number
When a unknown name is received; Unknown Name
When a unknown number is received; Unknown Number
When invalid data is received; Incomplete Data

The Caller ID list stores information for incoming calls - even unanswered calls. You can store up to 100 Caller ID messages and phonebook entries (including Speed Dials) for each handset and the base. You can view the Caller ID list through the handset or base during a call or when the phone is in standby mode.

Memory locations for Caller ID messages and Phonebook entries (including Speed Dials) are common, you can store up to all 100 entries for each handset and the base. Caller ID messages are not stored when you have 100 phonebook entries. When you have stored a total of 100 phonebook entries and Caller ID messages, the oldest Caller ID message is overwritten.

Please do rate the solution and revert for further assistance.


Thanks

Good luck!

It was changed automatically after someone left a message on caller ID.

I FIXED IT!!!  YIPEEE!!

What I did was UNPLUG the base's power unit from the wall... waiting about one minute, and plugged it back in.  That caused it to "reboot" the entire system, and the CID now shows itself.
