Newbee questions

That can be seemed a little ridiculous for most of you but the things is so.
I don’t have any experience with Linux and I need to write a plug in or something to asterisk server in order to adopt some of ours Windows solutions.
Can be used Debian Linux to install Asterisk? (because I have it)
Can I run Asterisk without special hardware to test voice over IP?

Thanks a lot of understanding.

Yes.

Yes, using just SIP or IAX protocols.

Cheers.
