Asterisk: Tools for peace and quiet

The topic of VoIP spam comes up every few months, and how to use Asterisk to combat the incessant and annoying stream of telemarketers who (despite my addition to the do-not-call list) continue to call my various phone numbers with “auto warranty” offers, “who’s who” directory sales pitches, or other suitably vague and sleazy offers.  This year has been particularly bad, with political campaigns calling my line sometimes four or five times in an evening.  I’d not call this VoIP spam (or SPIT, or vSPAM, or whatever you want to call it) at this point – it’s just the same … Continued

Wrapping OTTS at Digium HQ in Huntsville

It’s been fun having the Open Telephony Training Seminar here at Digium headquarters. Thanks to Phillipe, Tony, and Ethan for a power-packed week of training on FreePBX.

And that’s just the gravy: much of the week is spent in the meat of FreePBX, leaving students with a strong understanding of this flexible, hackable GUI for Asterisk and what it’s doing under the hood.

Here’s a photo from earlier today, with Tony talking … Continued

Economic Meltdown – Friend or Foe of Open Source

I considered looking at my retirement account balances today, but with the sinking feeling I got the last time I did this, I elected not to subject myself to that torture today. We are truly in the midst of a financial market meltdown of unprecedented proportion. The road kill became clearly visible here in Huntsville, AL on Monday with the sell of Wachovia, which had previously acquired Southtrust Bank – a bank with a broad investor base in the state whose linage can be traced back to its founding in Birmingham, AL in 1887. Many Alabamians watched in horror as … Continued
