Adding SIP URI Dialing to Asterisk for Free Worldwide Calling

Since giving up on Google Voice, we’ve been extolling the virtues of SIP URI dialing which gives you unlimited free calls to anyone else in the world that happens to have their own SIP URI address. SIP URIs look very much like email addresses except they’re used to share phone conversations instead of email messages. And, as we’ve mentioned previously, if everyone in the world had their own SIP URI, paying for phone calls would become a thing of the… Read More ›

Today we’re pleased to introduce a new state-of-the-art Travelin’ Man 3 firewall implementation for 2017. Five years ago, we developed a new security model for Asterisk® servers that whitelisted those needing access while blocking everyone else. The design was simple. You can’t attack what you can’t see. Three years ago, we made Travelin’ Man 3 more flexible for remote users with the addition of PortKnocker, a terrific tool providing temporary remote server access using a random three-number code.
