Voice Over IP (VoIP) - Another Example...
Voice over IP - that is, voice delivered using the Internet
Protocol is a term used in IP telephony for a set of facilities for managing
the delivery of voice information using the Internet Protocol (IP). In
general, this means sending voice information in digital form in discrete
packets rather than in the traditional circuit-committed protocols of the
public switched telephone network (PSTN). A major advantage of VOIP and
Internet telephony is that it avoids the tolls charged by ordinary telephone
service.
Example...
Intl. Calling Card - Another Example...
Calling cards are a prepaid method of making a long distance
(domestic or international) call. In using a calling card you save money on
your long distance phone bill. There are no monthly bills, no detailed
statements, and no hassles.
Example...
-
They are often much cheaper than long distance providers.
-
They are cheaper than your local phone company.
-
You can budget your long distance calling costs.
-
You can bypass hotel and educational institution systems with
the resultant savings. (Dialing phone card toll free access numbers allows you
to bypass the system.)
-
There are no monthly bills, and no detailed statements.
Rather, you simply pay for the calling time in advance and reduce the prepaid
balance as you make calls.
Voice Mail
- Another Example...
A computerized, highly sophisticated answering service that
automatically answers your call, plays a greeting in your own voice and
records a message. Depending on the sophistication of the service, it also can
notify you via a pager that you have received a call. After you have retrieved
your messages, you can delete them, save them, reply to them or forward them
to someone else on your voice mail system.
Example...
Instant Messaging (IM)
A service that alerts users when friends or colleagues are on line and allows
them to communicate with each other in real time through private online chat
areas. With instant messaging, a user creates a list of other users with whom
he or she wishes to communicate; when a user from his or her list is on line,
the service alerts the user and enables immediate contact with the other user.
While instant messaging has primarily been a proprietary service offered by
Internet service providers such as AOL and MSN, businesses are starting to
employ instant messaging to increase employee efficiency and make expertise
more readily available to employees.
