Is serverfault the most suitable stack exchange site for Asterisk questions?

I am using the unix & linux stack exchange a fair bit (it is easier to answer questions on it ;) but as asterisk is platform independent, would this site be a better place for it?

I am new to the community, so am trying to get my head around the differences between the stack exchange sites

I see a similar question was asked here, from this I take it that this is the best forum?
