Adding SIP URI Dialing to Asterisk for Free Worldwide Calling

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 ›

Having been around the block more times than we can remember, suffice it to say it takes a lot to get us excited about a VoIP provider. Let us tick off some criteria to even get our attention: terrific pricing, failsafe reliability, and first class performance. So just imagine our excitement to discover that an early follower of Nerd Vittles now provides one of the most compelling VoIP services we’ve ever tested with triple redundancy in multiple data centers. And… Read More ›

A Sobering Look at Asterisk and the 2019 VoIP Landscape

A Sobering Look at Asterisk and the 2019 VoIP Landscape

Every six months or so we like to gaze into our crystal ball for a quick look at the VoIP landscape. 2018 has been quite the transformative year with the acquisition of Digium® and Asterisk® by Sangoma®. Unfortunately, as we predicted, the Digium layoffs have already begun, and 2019 may only get worse. While we have no inside information, we wouldn’t be surprised to see Digium’s headquarters in Huntsville closed within six months in an effort to balance the books.… Read More ›

Spam Phone Call Blocker and CNAM Caching for FreePBX

Spam Phone Call Blocker and CNAM Caching for FreePBX

Blocking spam phone calls has been a challenge to put it charitably. Thanks to some earlier work by Stewart Nelson on the DSLR forum as well as Stewart’s considerable hand-holding in the development of today’s tutorial, we want to introduce a new approach to blocking these calls. The way it works is first time callers that pass the TrueCNAM SPAM check will be prompted to "press 5 to connect." Since most spam calls sit in a queue for several seconds… Read More ›

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 ›

Our last major Incredible PBX® upgrade on the Ubuntu platform supported Ubuntu 14.04 which was released in April, 2014. We skipped 16.04 because of all the wrinkles it introduced for VoIP deployments: an incompatible PHP upgrade, missing ODBC support, and on and on. Fortunately, all of those issues have been sorted out over the past two years, and several months ago we introduced Incredible PBX 13-13 for the Ubuntu 18.04 LTS platform which was released in April. Now we’ve added… 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 ›
