Server Configuration settings

What is the best setup for a Freepbx phone server. I am using a small business network, with a few remote SIP phones. I have a dell t105 server 500mb memory and a 80 gig hard drive. Is this sufficient and adequate for a good phone server?

Thank you for your assistance?

Yes, more than adequate.

I’ve certainly run an Asterisk system on less so that should work for a small system.
