I have been reading about Asterisk for a little while, and now I want to give it a test drive. If I have a Linux box running Asterisk, can I start making calls over my interenet connection? Can I make calls only to other PCs or to phones on PSTN?

Thanks for the reply.
What is the recommended specs for a server that will run a very basic PBX system?
