Some of the best reading at voip.ms is available only after login. So create an account (free!) and login and poke around some more.

If you like it, then deposit the $25 minimum via Paypal and grab a DID or two. Actually, request several, and then return the ones that aren't catchy numbers. It's only $2-3 or so per DID to do that.

And there are lots of cool tricks you can play with extra DIDs..

Cheers
