Then, why everybody doesn't use it yet?
Question Answer
Then, why
everybody doesn't
use it yet? Unfortunately we have to report some problem with the
integration between VoIP architecture and Internet. As
you can easy imagine, voice data communication must
be a real time stream (you couldn't speak, wait for many
seconds, then hear other side answering): this is in
contrast with the Internet heterogeneous architecture
that can be made of many routers (machines that route
packets), about 20-30 or more and can have a very high
round trip time (RTT), so we need to modify something
to get it properly working.
However with the new packets compression
technologies we can overcome the problem.
