or “ChgBat W/PowerOn” at Extensions 10 and 11
Possible Cause:

Display Does Not Show Caller ID Name/Number
Possible Cause 1:
Not receiving Caller ID service from local phone company.
What to do:
Contact your local phone company to check on Caller ID service.
■ If you are not receiving Caller ID service, subscribe to it.
■ If you are receiving Caller ID service, go to Possible Cause 2.
Possible Cause 2:
Extension connected to a module that does not support
Caller ID.
What to do:
Make sure lines with Caller ID service are connected to a PARTNER
ACS processor module, or 206EC, 308EC, or 400EC modules. If Caller ID lines
are not connected to one of these modules, install the appropriate modules and/or
make the appropriate connections.
Possible Cause 3:
Someone activated Call Coverage.
What to do:
Check the system phone display.
■ If
Coverage Call for XX
(where XX is the extension that activated the
Call Coverage) displays, the call is a coverage call. Call Coverage displays
the extension number of the person who activated the feature rather than
Caller ID information.
