Voice-over-Internet-Protocol
(VoIP)
is
an emerging technology that allows telephone calls, faxes, or overhead
paging to be transported over an existing
IP data network topology. Traditionally, voice and data were
carried over separate networks optimized to suit the differing
characteristics of voice and data traffic. With advances in
technology, it is now possible to carry voice and data over the same
networks while still catering for the different characteristics
required by voice and data. This provides for the addition of new
voice communications products without the need for installing new
cabling.
The
VoIP network could be:
A Local Area Network
A Wide Area Network
A Corporate Intranet
Or any combination of the above
IP is the predominate networking protocol used
globally. It presents a huge opportunity to dispense with separate
voice and data networks and use IP technology for voice traffic as well as
data. As voice and data network technologies merge, massive infrastructure
cost savings can be made as the need to provide separate networks for
voice and data can be eliminated. VoIP uses
connectionless, or packet, switching during a conversation. There is no
telling what path each packet might take to get to its destination. Once
transmitted these packets are
reassembled into their original order at the remote locations.
