My caller ID isn’t working.
Caller ID is a subscription service. You must subscribe to this service from
your telephone service provider for this feature to work on your telephone.
Your caller must be calling from an area that supports caller ID.
Both your and your caller’s telephone service providers must use caller ID
compatible equipment.
Make sure the home area code is set correctly in the telephone (see Home
area code on page 17).
If you subscribe to high-speed Internet service (DSL - digital subscriber
line) through your telephone line, you must install a DSL filter between
the telephone line and the telephone wall jack (see Telephone base and
charger installation on page 6). The filter prevents noise and caller ID
problems caused by DSL interference. Please contact your DSL service
provider for more information about DSL filters.
My telephone does not receive caller ID when on a call.
Make sure you subscribe to caller ID with call waiting features provided by
your telephone service provider. Caller ID features work only if both you
and the caller are in areas offering caller ID service, and if both telephone
service providers use compatible equipment.
A icon shows on the display and I don’t know why.
If appears on the display, then your telephone has received a signal
from your telephone service provider that you have a voicemail message
waiting for you to retrieve from your telephone service provider. Contact
your telephone service provider for more information on how to access
your voicemail.
I cannot retrieve voicemail messages.
If you subscribe to voicemail service from your telephone service provider
(charges may apply), contact your telephone service provider for more
information on how to access your voicemail.
