Caller ID
Description
A properly equipped system supports Caller ID, a service offered by the network telephone service
provider. The CO sends calling number information to the system after the first ring. Users with
display telephones can see Caller ID information as incoming calls ring at their extension. They can
also access previous calls via the Caller ID Call Log feature. The Caller ID number is recorded in
SMDR.
Prior to Version 3.0, the system would not display Caller ID information for an extension that was in
use when a call was received. In Version 3.0 or higher, Caller ID information is displayed on the
second line of an LCD display when an incoming call is received during conversation. If the second
incoming call is from another extension, the LCD displays the extension name or number.
