Yeah. I've never understood VoIP. As a remote access protocol, sure, but for an office? Why bother? There's existing equipment that works better and is cheaper.

Then again, Asterisk is really cheap. How much are the phones these days? Looks like about the same price as PBX phones. And you're not tied into a single vendor. And you can realistically administer it yourself. And you can avoid long-distance or trunk charges to a remote office. And you don't have to have a separate telco line for your voice.

Maybe it does make sense now.
