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.
With Version 5.0, the caller name (if available) can be displayed for a calls received from an
ISDN PRI line (ISDN / PRI NI II standard only).

•
Caller ID data is usually sent between the first and the second rings of the incoming trunk call.
The trunk may be programmed to immediately ring at the station or wait until after the Caller ID
digits are received before ringing at the station. If the trunk is programmed to ring immediately,
the Caller ID digits will not display until after they are received and processed.
•
Caller ID numbers may be denied from being sent for some callers (private). Some long distance
carriers may not provide Caller ID data (out of area).
•
Prior to Version 3.5, Caller ID supported only the number format. Version 3.5 and higher
supports selection of the number or name.
•
In Version 3.5, Caller ID displays the highest ringing priority call (
call queued to ring at the
target extension immediately after the present call terminates
).
Caller ID Alpha Tagging
Description
If the received Caller ID phone number matches any number in the System Speed Dials (SSD000-
SSD199), then the associated System Speed Dial name can be displayed as the Caller ID information.
Alternatively, the DID name may be displayed instead.
In Version 3.5 and higher, Caller ID information will be shown on the second line of the LCD display
when an incoming call rings a display phone with a conversation already in progress. Second
incoming calls include extension Camp-on, extension Call Wait, queued DIL, both Appearance and
non-Appearance calls (CO, MCO, virtual or DN, recall, BLF).
