Troubleshooting
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 phone.
The 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.
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 cord and the telephone
wall jack. The filter prevents noise and caller ID problems
resulting from DSL interference. Contact your DSL service
provider for more information about DSL filters.
System does not receive caller ID when on a call.
Make sure you subscribe to caller ID with call waiting features
from 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.
I subscribe to a nontraditional telephone service that uses
my computer to establish connections, and my telephone
doesn’t work.
Make sure your computer is powered on.
Make sure your Internet connection is working properly.
Make sure that the software is installed and running for your
nontraditional telephone service.
Make sure to plug your USB telephone adapter into a
dedicated USB port on your computer. Do not plug it into a
multiple port USB hub (USB splitter) that is not powered.
