Probable Cause
Corrective Action
Your organization does not
subscribe to caller ID service
or you have DSL phone lines
without filters installed.
Caller ID is a subscription service. You must
subscribe to this service from your local
telephone service provider for this feature to
work on your phone.
The caller must be calling from an area that
supports caller ID.
Both you and your caller’s telephone companies
must use caller ID compatible equipment.
If you have DSL phone lines, confirm that you
have a DSL filter plugged in between each
Deskset and DSL wall jack. The DSL filter must be
plugged into the wall jack, not the Gateway.
