| VoIP (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. |
