I hear other calls when using the cordless handset.
Disconnect the telephone base from the telephone wall jack. Plug in a different
telephone. If you still hear other calls, the problem is probably in the wiring or telephone
service. Call your telephone service provider.
The other party cannot hear my voice during a call.
Make sure the mute feature is not turned on during a call (page 20).
Registration failed appears on the handset.
You may already have 12 handsets which the system can accommodate. See Expand
your telephone system on page 59.
Follow the steps on Common cure for electronic equipment (page 67), then try again
to register a handset.
My caller ID features are not working properly.
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.
The caller may not be calling from an area which supports caller ID.
Both your and your caller’s telephone service providers must use equipment compatible
with the caller ID service.
The caller ID information shows after the first or second ring.
If you subscribe to high-speed Internet service (digital subscriber line - DSL) through
your telephone line, you must install a DSL filter between the telephone line cord and
the telephone wall jack. The filter prevents noise and caller ID problems caused by DSL
interference. Contact your DSL service provider for more information about DSL filters.
The telephone does not receive caller ID or the telephone does not show caller ID
during call waiting.
Make sure you subscribe to caller ID with call waiting features provided by your
telephone service provider.
The caller may not be calling from an area which supports caller ID.
Both your and your caller’s telephone service providers must use equipment compatible
with caller ID service.
