Caller ID Overview

Caller ID (sometimes called CLID or ICLID for incoming call line identification) is an analog service offered by a central office (CO), which supplies calling party information to subscribers. Typically, the calling party number, and sometimes the name, appears on a station (also called extension) device such as a PC telephony software application screen or the display on a telephone. Type 1 caller ID provides the calling party information while the call is ringing, and Type 2 caller ID provides the additional convenience of calling number display while the recipient is on another call. In this release, Cisco provides only Type 1 caller ID support.

The caller ID feature supports the sending of calling party information from foreign exchange station (FXS) loop-start and ground-start ports into a caller ID equipped telephone device. The FXS port emulates the extension interface of a private-branch exchange (PBX) or the subscriber interface for a CO switch.

The caller ID feature supports receiving calling-party information at foreign exchange office (FXO) loop-start and ground-start ports. The FXO port emulates a connection to a telephone and allows connection to a PBX extension interface or (where regulations permit) a CO subscriber line.

The following are benefits of using caller ID:

•Enterprises—Caller ID is invaluable for increasing efficiency through its use in computer telephony integration (CTI) applications, where for example, calling party information can be used to retrieve client information from a database when a customer call is received.
