What is VoIP?
Question Answer
What is VoIP?
The past: More than 30 years ago Internet didn't exist.
Interactive communications were only made by
telephone at PSTN line cost. Data exchange was
expansive (for a long distance) and no one had been
thinking to video interactions (there was only television
that is not interactive, as known).
Yesterday: Few years ago we saw appearing some
interesting things: PCs to large masses, new
technologies to communicate like cellular phones and
finally the great net: Internet; people begun to
communicate with new services like email, chat, etc. and
business reborned with the web allowing people buy
with a "click".
Today: Today we can see a real revolution in
communication world: everybody begins to use PCs and
Internet for job and free time to communicate each
other, to exchange data (like images, sounds,
documents) and, sometimes, to talk each other using
applications like Netmeeting or Internet Phone.
Particularly starts to diffusing a common idea that could
be the future and that can allow real-time vocal
communication: VoIP.
The future: We cannot know what is the future, but we
can try to image it with many computers, Internet almost
everywhere at high speed and people talking (audio and
video) in a real time fashion. We only need to know what
will be the means to do this: UMTS,
VoIP (with video extension) or other? Anyway we can
notice that Internet has grown very much in the last
years, it is free (at least as international means) and
could be the right communication media for future.
