We weren’t sure we would ever be writing this column. And, if it weren’t for @NAF of DSL Reports fame, it might very well have been years before a SIP-compatible version of Google Voice was available for Asterisk®. We really can’t overstate the scope and enormity of his accomplishment. If you look at NAF’s code additions to Asterisk, you’ll understand why.
