◊ DID YOU MEAN IP TELEPHONY?
IP Telephony
(IPT, Internet Telephony) Use of {IP} data
connections to exchange {voice} and {fax} data that have
traditionally been carried over the {public switched telephone
network}.
During the late 1990s, an increasing number of telephone calls
have been routed over the {Internet}. Calls made in this way
avoid PSTN charges. Unlike traditional telephony, IP
telephony is relatively unregulated.
Companies providing these services are known as {Internet
Telephony Service Providers} (ITSPs). They include telephone
companies, cable TV companies and {Internet Service Providers}
(ISPs).
There are still many problems with voice quality, {latency},
{compression} {algorithms}, and {quality of service}.
{Voice over IP} is an organised effort to standardise IP
telephony.
See also {Computer Telephone Integration}.
