Caller ID Functions 4-7

Caller ID Functions Caller ID is a service provided by local telephone companies. When you subscribe to caller ID, your phone company begins providing you real-time information about incoming calls.

The caller ID signal includes the date and time of the call, the phone number of the calling device, and, optionally, the name of the calling party. The signal is sent between the first and second rings and must be decoded and displayed by a device connected to your phone line. The Business Modem has the ability to decode and display the caller ID information.

Service Types You can subscribe to Basic or Extended caller ID service. Basic service offers you the date and time of the call and the calling party’s telephone number. Extended service provides the billing name associated with the calling party’s telephone number in addition to the Basic service information.

The information the Business Modem actually receives depends on the service type to which you’ve subscribed, the information that the calling party’s telephone company provides, and whether the equipment in between supports caller ID. At minimum, you will always receive the date and time that a call arrived.

If a call arrives without a caller ID signal, the modem will send OUT OF AREA in place of the phone number and name. If the caller ID information has been blocked by the user at the other end, the Business Modem will send PRIVATE in place of the phone number and name.

Applications of Caller You can use caller ID to screen calls, keep a record of calls, or prevent ID Technology unauthorized access to your network. Third-party database and

telephony applications such as security, call logging, and black-listing applications exploit the caller ID information provided by the Business Modem.
