Most common employed
voice solution is VoIP. VoIP is Voice over Internet
Protocol and is also termed as IP Telephony, Internet
telephony, Broadband telephony, Broadband Phone and
Voice over Broadband. VoIP is generally described as
the routing of voice conversations over the Internet
or through any other IP-based network. VoIP, or Voice
over Internet Protocol, is a method for taking analog
audio signals, like the kind you hear when you talk
on the phone, and turning them into digital data that
can be transmitted over the Internet. Voice over IP
protocols carry telephony signals as digital audio,
typically reduced in data rate using speech data compression
techniques.

Another commonly
employed voice solution is EPABX/PA. EPABX is Electronic
Private Automatic Branch Exchange and most commonly
abbreviated as PBX i.e. private branch exchange. Thus
it allows all users to share a certain number of external
phone lines. The typical EPABX can also switch calls
between a VoIP user and a traditional telephone user,
or between two traditional telephone users. With a conventional
PBX, separate networks are necessary for voice and data
communications. |
