3com SuperStack 3 NBX Manual De Usuario

On a single NBX 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.

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

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

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.

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.

If A1 calls A2 who then forwards the call to B1 over a Virtual Tie Line 
connection, the Caller ID information for A2 appears in the display panel 
on B1’s telephone. The Caller ID information includes the IP address of 
NBX system A and the extension number of A2.

When someone performs a blind transfer to a hunt group, telephones in 
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 appears.
