A very stupid question

Hi all,
I have installed asterisk in my unix box at home and would like to use it not with my phone line but with my voip line. I have bellsouth dsl and have signed up with Sunrocket for my voip service. They sent me a device that connects to the router and to the telephone. Can I use asterisk with this setup?

I would go to dslreports.com and look for the sunrocket forum on the voip forums, and search there. there have been questions about using SR with asterisk, I seem to recall.
