I read thru the manual. There is nothing bout recovery of factory messages. If you recorded your own, try deleting it. Or unplug the base from power and try a reset. This is from the manual. At the end, I gave you a link to the manual!

For voice mail service subscribers
If you subscribe to a flat-rate service
package that includes Caller ID, call
waiting, voice mail, and unlimited
local/regional/long distance calls, please
note the following:
L To use the voice mail service provided
by your service provider/telephone
company rather than the unit's
answering system, turn off the
answering system (page 30).
L To use this unit's answering system
rather than the voice mail service
provided by your service provider/
telephone company, please contact
your service provider/telephone
company to deactivate your voice mail
service.
If your service provider/telephone
company cannot do this:
- Set this unit's "Ring count"
setting so that this unit's answering
system answers calls before the
voice mail service of your service
provider/telephone company does.
It is necessary to check the number
of rings required to activate the
voice mail service provided by your
service provider/telephone
company before changing this
setting.
- Change the number of rings of the
voice mail service so that the
answering system can answer the
call first. To do so, contact your
service provider/telephone
company.

You did record a message on the answerer, didn't you? Mine displayed that until I recorded the outgoing message for the answerer. You do not need any service from your phone provider. The answerer in the base unit simply records the caller's message when you don't answer after a set number of rings. The manual tells you how to name the handset, which is a nice feature if you don't wish to use "unit 1, unit 2, etc".
