I received a voicemail from an unknown caller, but no missed call so I cannot figure out how to call them back and talk further

If you have 3 way calling ,you should be able to do that, as long as you are talking voicemail and not the answering machine, flash your receiver and dial voice mail, flash and join calls, you should be able to hang up and they will be to your voicemail.

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

Once you figure out what voicemail this is, you will need to go into Voicemail Admin Programming to re-initialize the password for an extension.

I just called my service provider and they were able to fix it. Just gotta wait 4hrs then turn it off, wait a few seconds then turn it on. heaps quick they knew what i was talking about straight away

You must turn off Automatic extension Privacy off on the voicemail extensions. If you have no idea what that is, then I would suggest calling in a local vendor, as it is a little difficult to do over a forum...

Contact your mobile service provider's helpdesk for further assistance on activating your VM

Some network providers are having trouble with caller id. You need to be sure that friends or callers are not putting code for unknown caller. Automatically You receiving as unknown calls.
Check Your phone on setting caller id click on show.

quick way is to delete them both and re-record
