[asterisk-users] Asterisk conferencing features

[Rafael Marangoni]

Hello!

I'm new in Asterisk and I hope that my trouble is very simple.

We're implementing a Education Project of a e-Learning system (LMS)
that uses conferencing (video and audio) over internet.

The e-Learning system will be on GPL license, and for that, we're
using only free software to implement.

Asterisk is our first choice for video and audio conferencing, and
making tests, started to implement it.

The questions are:

1. Asterisk makes sip conferencing? (I know the aswer is yes)

2. Asterisk need Digium hardware to do that ? On asterisk handbook I found:

"Note that for technical reasons, you must have at least one Zaptel
interface (of any kind) installed in your Asterisk system if you wish
to use conferencing." (page 7)

3. Asterisk make video conferencing?

4. If yes, anyone have docs more detailed on how to do that?

5. Anyone know clients (softphones) under gpl that we can use the code
to implement on this aplication?

I need asterisk only for internet conferencing, and I know that it's
much more than that.

Thanks, and sorry for the questions
