There are many commercial voicemail transcription services for Asterisk® PBXs, but none hold a candle to the speech-to-text (STT) quality of the IBM Cloud offering known as Watson® STT, formerly known as Bluemix TTS. Despite a recent price increase that takes effect in December, the pricing remains competitive. On the Standard Pricing Plan, voicemail transcription is 2ยข per minute. Or you can try things out on the LITE plan which offers 100 minutes a month at no cost. When the… Read More ›

Whether you’re new to VoIP technology or an Old Timer, nothing is quite as frustrating as wrestling with one-way audio and no audio on SIP calls either because of poorly designed NAT-based routers or poorly implemented SIP ALG solutions on low-end residential routers. To make matters worse, you get to deal with calls originating behind not one, but two, NAT-based routers neither of which complies with the basic SIP Rules of the Road. In a perfect world, SIP and RTP… Read More ›

We’ve been scratching our head for a good way to commemorate Micro$oft’s $7.5 billion purchase of GitHub which has served as the linchpin of the open source development community for many years. We’ll leave it to others and history to judge whether this was a good idea or not. What we came up with was a GPL Toolkit for Incredible PBX 13-13 that makes it child’s play to upgrade FreePBX® GPL modules in our Incredible PBX® 13-13 offerings for CentOS/SL,… Read More ›

In the lead up to the demise of Google Voice XMPP service next week, we wanted to offer what we have found to be a cost-effective SIP strategy which takes advantage of the best of all worlds. We would divide SIP offerings into five broad categories: business-class unlimited SIP trunks, Old Faithful SIP providers, Mom-and-Pop SIP services, dirt-cheap termination services, and Gee Whiz SIP providers. As we have said many times, the beauty of setting up an Asterisk® PBX such… Read More ›

It’s been more than 10 years since we first introduced CallerID Trifecta for Asterisk® and the FreePBX® platform. A few months later it morphed into CallerID Superfecta and, as they say, the rest is history. Today CallerID Superfecta is used by over a million people around the globe to obtain CallerID Name (CNAM) information from over 70 different lookup sources. WOW! Just call me the Proud Papa. What a journey it has been, and our special thanks to the dozens… Read More ›

Since Asterisk® will no longer be able to "talk" to Google Voice after June 17, we promised to hold our nose and document how to salvage your Google Voice trunks. Our exercise for today is to show you how to deploy an OBi 200-series device which can speak the new Google Voice language and use it as a traditional SIP bridge between Google Voice’s proprietary SIP platform and your Asterisk server. We will skip the editorializing on why Google is… Read More ›

If you’ve been waiting for a low-cost, feature-rich SIP phone that meshes perfectly with your Asterisk® PBX, your prayers have been answered.

Digium gave us a couple of early models to play with, and today we’ll walk you through the incredibly simple setup. We would begin by noting that, despite the pricing, these phones are configured with nothing resembling… Read More ›
