Specific Caller ID Situations 503

Internal Calls

On a single system, user A calls B who transfers the call to user C. In C's
telephone display panel, the top line contains Caller ID information for A
and the bottom line contains Caller ID information for B.

Nortel Phones

If you have Nortel telephones connected to your system using the Nortel
interface card, the behavior of Caller ID on these telephones is identical
to the behavior on 3Com telephones.

Parked Calls

When you retrieve a parked call, the Caller ID associated with the call
displays for approximately five seconds in your telephone display panel.
You do not see the Caller ID of the person who parked the call.

Second Incoming Call

If you are currently involved in a call on your telephone and another call
arrives, for approximately five seconds you see "Incoming Call" on the
top line of the telephone display panel and the Caller ID of the incoming
call displays on the bottom line.

TAPI Calls

If a call is forwarded to a telephone that is controlled by TAPI software,
both the original Caller ID and the Caller ID of the person forwarding the
call are sent to the TAPI software.

TAPI Redirected Calls

If telephone A is being monitored by an external TAPI application and a
forwarded call to A is redirected to telephone B, the TAPI software passes
the Caller ID of the original caller and the Caller ID of the forwarding
telephone to telephone B.

VTL Calls

If A1 calls A2 who then forwards the call to B1 over a Virtual Tie Line
connection, the Caller ID information for A2 displays in the display panel
on B1's telephone. The Caller ID information includes the IP address of
System A and the extension number of A2.
See "Adding VTL Devices to the Pretranslators (Optional)" on page 338
for information about how to remove the IP address from the Caller ID
information or change it to the VTL site code for that site.
Calls Transferred to When someone performs a blind transfer to a hunt group, telephones in
Hunt Groups the hunt group display the called ID information of the original caller on
line 1 and the hunt group name and number on line 2. After a hunt
group member answers the call, only the caller ID information of the
original caller displays.
