AstriCon 10: WOW! What a Coming Out Party for Asterisk 12!

It was the tenth anniversary of AstriCon in Atlanta this week with an SRO crowd, and what a week it was. Comparing Asterisk® 12 to Asterisk 11 and previous iterations would be much like comparing Windows 8 to Windows 3.1. Facelift doesn’t begin to describe the metamorphosis. There’s a brand new (robust) SIP implementation featuring PJSIP, and a new restful interface known as ARI that lets you get at all of the Asterisk internals with a simple web command.

How far we have come! The original Asterisk® claim to fame was its ability to interface with proprietary phone systems and legacy telephony hardware, the glue that literally kept companies stuck to their overpriced PBXs. And, just as wired phone systems began to lose their edge, along came the Bell Sisters to introduce cellular communications with billing that began when the phone started ringing and an end to toll-free calling and extra fees for text messaging on top of exorbitantly… Read More ›

The 5-Minute PBX: Introducing PIAF-Green Virtual Machine for VMware ESXi

In our never-ending trek to build the Perfect PBX™, we have another installment for you today featuring VMware’s just released vSphere Hypervisor 5.5 (ESXi). And, yes, there’s still a free ESXi version with a free license available here. But, unlike VirtualBox, you’ll need a dedicated (beefy) server on which to install ESXi. Be sure to register on the site and obtain then install the unrestricted license, or you’re SOL after the short eval period. We’ve built an ESXi appliance which… Read More ›

[soundcloud url="http://api.soundcloud.com/tracks/110813303″ params="" width=" 100%" height="166″ iframe="true" /] It’s been a while since we looked at the text-to-speech (TTS) landscape with Asterisk®. So we thought we’d bring you up to date on where we stand with text-to-speech in the free department insofar as Asterisk 11 is concerned. The hands-down winner remains Lefteris Zafiris’ implementation of Google TTS. It rivals any commercial TTS software application and costs you nothing. The good news is, if you’re running Incredible PBX 11, you already… Read More ›

It’s been over 7 years since we first wrote about streaming music on hold with Asterisk®. While we’re energized with Back to School Fever, we decided it was about time for a refresher. And, in honor of TWOfer Tuesday, we also have a terrific new SIP discovery to share. It won’t cost you a dime. For long time readers of Nerd Vittles, you will note that all of the MOH syntax has changed since the early Asterisk days. So today… Read More ›

Practicing Safe SIP: Adding SIP URI and Free DID Connectivity to Asterisk

Practicing Safe SIP: Adding SIP URI and Free DID Connectivity to Asterisk

Last year, we began our exploration of safe SIP options for Asterisk® by introducing a hybrid solution using VoIP.ms for a registered SIP trunk and IPkall for a free DID. Today, in addition to a free IPkall DID to accept incoming PSTN calls, we have a slightly different approach that provides a direct SIP URI address from Sip2Sip.info for your server. As with the original tutorial, today’s implementation preserves our Zero Internet Footprint™ design for total SIP insulation of your… Read More ›
