Internet Telephony
 |
Internet telephony
refers to communications services-voice, facsimile, and/or voice-messaging
applications-that are transported via the Internet, rather than the
public switched telephone network (PSTN). Quite simply, a VOIP system
is a telephone system that transmits over your computer network cabling.
|
The basic steps involved in
originating an Internet telephone call are conversion of the analog voice
signal to digital format and compression/translation of the signal into
Internet protocol (IP) packets for transmission over the Internet; the
process is reversed at the receiving end.
