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 ›

Since Google removed XMPP support and transitioned to their new GVSIP platform, many have held out hope that Google hadn’t moved to a purely commercial platform with their ObiHai deal. Yesterday, the head of the Google Voice project requested that all Asterisk GVSIP implementations be discontinued citing Google’s Terms of Service. We hinted this was coming back in July and… 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 2¢ 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 ›

One of the first things you’ll need if you choose to migrate to FusionPBX and FreeSWITCH is voice prompts. You can record your own in FusionPBX using the Recordings application by dialing *732. Of course, your PBX will probably sound like you recorded your own prompts. 🙂 Our first recommendation is to always direct folks to Allison Smith whose voice prompts for Asterisk are legendary. But, for those on a tight budget, recordings by a professional voice talent may not… 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 ›
