If you’ve installed Asterisk® during the past 4½ years, your server has a MAJOR security problem. If you didn’t already know, with Asterisk, your VoIP conversations actually are carried over a random UDP port using the Real Time Protocol (RTP), not the SIP port (UDP 5060) which handles the setup and teardown of your VoIP connections.

The Internet is all about sharing the best finds and once a year we like to take a fresh look at what’s new and exciting whether you travel frequently or not. While the primary focus of Nerd Vittles is VoIP technology, you can’t provide the best VoIP solutions without also exploring network and cellular technology.

Last week we introduced the new (free) version of PIAF5 powered by 3CX v15.5 supporting four simultaneous calls, unlimited trunks, 10 extensions, and 10-user conference calls. And today we’re torture-testing our new 3CX server in the Bahamas aboard one of Carnival’s 3,000-passenger floating cities. Somebody’s gotta do it, right? What makes this such a challenging test for any PBX are several things. First, we’re using a free Google Voice trunk on a free 3CX PBX that we configured in under… Read More ›

In a word, WOW!

Well, it’s been an interesting week. RingPlus, a Sprint MVNO, has gone belly up after Sprint pulled the plug on them. Lawsuit details are here.

We kick off 2017 with a new series on autonomous vehicles and, for the short term at least, the focus will be on Tesla simply because they’ve moved the needle the quickest and have a billion+ driver-tested miles under their belt already.
