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.

Does my computer have to be turned on? 
Question 
Answer 
Does my computer 
have to be turned 
on ? 
I f you finished the VoIP setting with the VoIPMaster 
260W and you can use the phone to dial directly. So 
your computer does not need to be always on.
