Digium's Mark Spencer Guest On FLOSS Weekly

The TWiT guys posted a podcast with Mark Spencer just a couple of days back. Over an hour long. Pretty cool stuff. Mark's such a nice guy to be also such a visionary.

Asterisk and FreeSWITCH

This week I'm using some link bait which discusses a few of the differences between Asterisk and FreeSWITCH. David Greenfield wrote a short blog post discussing one particular case study where FreeSWITC… Continue

A couple AsteriskNOW tutorial chapters

I just got some tutorial chapters from PackT Publishing’s AsteriskNOW book by Nir Simionovich. Although most OS-VoIP readers aren’t developers, and the ones who are probably rarely use AsteriskNOW, I figured there’s no… Continue

Premise based Open Source IP PBX or hosted VoIP?

This is a question I hear constantly and the answer typically relies on three things - cost, business size, and required functionality. Most small-mid sized businesses exploring the move to a new phone system will consider the ups and downs between purchasing a premise based IP PBX or a hosted VoIP solution. These days I think purchasing an old TDM phone system instead of an IP based system is about as smart as buying a VHS… Continue

74 Open Source VoIP Apps

At some point I’ll be writing a full article on the squillions of Open Source VoIP apps out there but until I find the time to do so, I want to share with you all this list called 74 Open Source VoIP Apps & Resource. Here at OS-VoIP, one of the things I’m trying to do is help individuals differentiate between Open Source VoIP apps that are ready for the enterprise and which ones are not. A lot… Continue

Exactly 1 month left to submit for Digium Innovator Award

The second annual Digium Innovation Award is coming up folks! The deadline for your submissions is August 1st so don’t forget. This award was created last year to showcase all the “innovative” applications for which Asterisk can be used. Those eligible for the award are all Digium|Asterisk customers and partners world-wide with solutions that are live or in production. This is nice and broad so if you’re working on something that warrants an “innovative”or “never done before” title, then I enco… Continue

Choosing Open-Source Telephony.

I stumbled upon this article on eWeek which was written by Sangoma CEO, David Mandelstam. This short paper discusses a few things that I consistently have to re-iterate to every client when selling an Asterisk based PBX. Hopefully now this article should save me some time. It is articles like these that truly help out the sales process because they provide the consumer with a no-bull-shit explanation abo… Continue

An Odd Confluence Of Events; VoWifi, Calliflower, Airlines & William Shatner

I spent much of this past week in Los Angeles. I was all set to fly home Friday morning but my last meeting canceled so I got myself on the last flight out Thursday evening, a 6pm departure. Except it wasn't. Thunderstorms in Houston, and bad weather elsewhere in the east, had caused a myriad of delays and cancellations. My 6pm departure was pushed back until almost 9pm. No big deal. No point in making a fuss. It was still better than killing the next day getting home. Besides, I could use the… Continue

Blocking Telemarketers in Asterisk with whocalled.us

Don't you wish there were a community driven database of telemarketers you could use to automatically block them? Well there is! The great people over at whocalled.us have just that, and they even provide a web API which allows you to check numbers against. The code below will check the number against the API and assign the SPAM variable to yes if it has been reported more than 5 times. (Sorry about the code formatting in this post): #!/usr/bin/perl use strict; use Asterisk::AGI; use LWP::Sim… Continue

Asterisk Pseudo Toll Fraud Detection

So I was bored in a teleconference and re-did something I started a while back. Are you all watching your logs? Do you know who's connecting or at least trying to connect to you? Do you have implicit firewall rules stating who can and who can't connect to your PBX? Since I do a lot of trunks on a carrier level as well as have a slew of managed boxes, it becomes difficult creating all inclusive rules especially when my clients have remote workers. So whats the next best thing in order to stop th… Continue
