Asterisk on Mac OS X

I have a mac mini with Snow Leopard Server installed. I am wondering if there is a possibility to install asterisk on it and taking in consideration that I cannot plug in any card if there is a possibility to buy some hardware to connect that server with the local land line phone.

Thanks in advanced for your answers.

The least troublesome solution would be to use VM WARE Fusion, and create a new virtual machine using the ISO.

If it possible that install an asterisk on a Mac OS directly…

it is possible to install asterisk on mac os X using macport. the only problem is that there is no dahdi support therefore no conferencing possibility.
