We take the fairly good audio quality in a telephone conversation
for granted. Telephone calls over the Internet is not that easy,
as millions of data packets must cross dozens of servers just to
make one single conversation. yellowTAB has therefore chosen two
well tested stacks for the included VoIP application: OpenH323
and RTP-RCTP.
The H.323 ITU standard allows you to make audio and video calls
to remote users with H.323 hardware or software (such as Microsoft
Netmeeting and GnomeMeeting for Linux and various unixes).
BeNet lets you can carry on voice or videoconferencing sessions.
It uses full-duplex audio technology, so that you and a friend can
talk at the same time without interruptions. The audio codecs (compression/decompression)
used minimize feedback loops and delivers great voice quality.
BeNet only lets you call other PCs using OpenH323 or RTP/RCTP,
saving you from paying long distance telephone rates. Calls to regular
telephones can not be done from within this application.
Hardware Requirements
First of all you need a sound card that has supported input
and output. These are configured in the Media
Preferences.
You then need at least a microphone and a set of loudspeakers.
We recommend a headset that includes a microphone.
When it comes to the Internet connection, the minimum requirements
for the chosen audio codecs are broadband.
Configuring BeNet
BeNet's Preferences is devided in to four panels (tabs): General,
Audio, Network and Identity.

General is controlling how the user interface is built up
in the main window. Activating the check boxes, activates parts
in the main window. The parts in the main windows can all be minimized.
The changes you make here, will first take effect the next time
you start up.

Audio: Depending on your internet connect you should activate
Use codec and Modem Quality. Using a modem slows down
the speed of the transmission.

Network: This panel lets you choose to make BeNet go online
on startup.
You can enter the IP of your IP Server (if you know one) and port
to connect to (it should always be 3030). Also, you can set timeout
(5 minutes is the default) for your connection to the IP Server.

In the Identity panel you should identify yourself, so that
others know who is trying to contact them.
