Interactions for Caller ID

Last Updated : Oct 30, 2012 |

This section provides information about how the Caller ID feature interacts with other features on the system. Use this information to ensure that you receive the maximum benefits of Caller ID in any feature configuration.

Attendant Display Features

A call that is redirected to either the attendant or the attendant queue causes the display on the station of the attendant to match that of the station display of the connected party.

Automatic Display of Incoming Call Identification

If a new call comes in while the station user is off-hook and connected to a call, the display automatically shows the new incoming call identity for 30 seconds. After 30 seconds, the display returns to the identity of the original call. If the system redirects the call after a few rings, the display returns to the identity of the original call. If the system shows a new incoming call, and then that call drops, the display returns to the identity of the original call.

Bridged Call

The system shows incoming call identity on both the primary station and the bridged station.

Call Forwarding

Forwarded-From Station Display

The system does not show any information on the station of the called principal.

Forwarded-To Station Display

The system shows the identity of the calling party and the called party, and the reason (R) code. If the forwarded-to station is on a different switch, the system does not forward the called party information.

Call Pickup

Called Party Station Display

Shows the identity of the calling party.

Answering Party Station Display

If Call Pick-Up answers a Caller ID call, the system shows the identities of both the calling party and the called party.

Call Coverage

Called Party Display

The display of the called party shows the identity of the calling party until the coverage party answers the call. If the coverage party answers the call, the station display of the called party goes blank. If the called party temporarily bridges in after the coverage party answers the call, the displays of the coverage party and the called party change to indicate a conference call.

Coverage User Station Display

The station display of the coverage user shows the same display as the station display of the connected party.

Call Vector Routing

When a Caller ID call coming from analog trunks transfers to a Vector Directory Number (VDN), the incoming calling number is directed to that VDN so call vector routing can be based on the caller ID information.

The Automatic Number Identification (ANI) that is received for the incoming call, by way of inband signaling or ISDN, is forwarded with a route-to step over a trunk that supports inband or ISDN ANI delivery.

Distributed Communications System (DCS)

If Communication Manager has both DCS and Integrated Services Digital Network (ISDN) displays, the system shows the caller ID information in DCS formats.

Hold

When Hold is activated, the display becomes blank. The party who activates the Hold then reads the identity of the newly connected party. The display of the held station remains unchanged. When the party deactivates the Hold, the system refreshes the display to indicate the current state of the call.

Malicious Call Trace (MCT)

When MCT is activated for a particular call, the system displays incoming calling numbers to controller stations.

Tandem Operations

The system passes the calling party name and the calling party number to the terminating server over ISDN trunks with DCS Plus (+).

Transfer

When the system transfers an Caller ID call, the display of the transferred-from station becomes blank. The display of the transferred-to station shows the identity of the transferred-from party if the transfer is not yet complete. Once the transfer is complete, the transferred-to station shows the identity of the calling party.
