Skype has it's own VoIP protocol. and it does not use any common
protocol such as SIP, H232 etc...
The Skype codec is high-availability codec, that is, it attempt to
compress the audio (and video) and giving your CPU to work a lot more,
while trying to keep law bandwidth.

hmm... nope. Not really.
Skype uses a proprietary wide band codec supplied by a third company

It might. Technically a super-node in skype speak rather then the

There are several standards, open and closed.
Skype specifically is a closed proprietary protocol that uses an idea
similar to file sharing. The calls don't go through servers, the data passes
over relaying clients and where the clients are is not assured.
It probably depends on which providers
It probably depends on which providers the clients are sitting on but the
data should probably not go through Europe, I'm guessing that there's a
higher chance it will go through the states and if one of you is on a
university network it might happen as well, but local providers, unless it

Perhaps they're using it for interfacing with the PSTN?

The short answer is not necessarily.
1. Skype calls do not go through a central server. A central server is
used to keep track of people's status etc.
2. If both ends of

Assuming that Skype is in fact using iSAC as stated by other posters, this
would be the codec used for PC to PC cals. According to the developer's
spec sheet, iSAC provides 16 kHz sampling using a bitrate of 10kbps to
32kbps.
The skype link you gave me, is good. Found a lot of interesting things there.
Ill check more about QoS of voip. 39% is not enough. That's from a
web page that checks voip quality.

Hi guys,
I found the solution!
I had given up on this a while ago and was now installing fedora 9 on my
laptop and came across this same flash problem where the sound would not
work. After trying a few more things I found this very simple solution (at
least for Fedora). You just need to install

Of course, Skype does other things apart from voice communications, and if
you have a connection able to act as a supernode then Skype may decide to
use it as such,
I checked the specification. Looks like they apply a good codec which
is supposed to overcome slow bandwidth. yet I still have problems.
People barely can hear me.

Can you hear yourself? Did you run an echo test?

My wife and I used Hot/Barak from late April 2007 to late April 2008.
Yes, I can hear myslef. But the volume is much lower than what I
speak. I bought some muller headset from supersal big. I checked all

Thanks, I will try it. I even disabled the web camera because it used
almost 90% CPU. I have now version 2.0.0.63 (latest version on gentoo
is 2.0.068). When I talk I see that jitter jumps to high values.
sometimes 600-750.
