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
ID Technology
You can use caller ID to screen calls, keep a record of calls, or prevent
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.
