About the author

Mark Spencer founded Digium®, Inc., in 1999 as Linux Support Systems while still a computer engineering student at Auburn University. When faced with the high cost of buying a PBX for the company, Spencer simply used his Linux PC and knowledge of C code to develop his own PBX. This was the beginning of the worldwide open source phenomenon known as Asterisk®. As Asterisk gained in popularity, Spencer shifted his business focus from Linux support to supporting Asterisk and opening up the telecom market. Mark renamed the company Digium and transformed the fledgling upstart into the leading open source telecommunication provider in the world today. As the Chairman and CTO of Digium, Mark Spencer continues to drive the strategic vision and technology direction of the company as well as focus on the development and growth of the Asterisk Community at large. Spencer is widely regarded as the pioneer of open source telephony and gives frequent keynote addresses to large technology audiences. Mark on google+

Video: Mark Spencer on IP Phone App Development

If you’ve ever wanted to learn about the Digium phone API, or if you’ve ever wondered just how many freckles I have on my face, this is the video for you!  I spent some time working with Billy Chia on building an app on the Digium Phone API.  I’ll also release this sample code, and go through a code walkthrough, during my session at Digium Asterisk World in Miami (later this month). Amazingly, Billy was able to coauthor this code as his very first software development experience. Not bad for someone from marketing, right?  So much for the Golgafrinchan’s “B” Continued

Awards and Astricon!

Again it’s starting to be that time of year where AstriCon http://www.astricon.net is becoming visible on the horizon.

This year promises again to be a record-breaker – we’ve already got
more pre-show signups, more participants on the show floor, and a
fantastic line-up of speakers and sessions.  There will even be a job
fair for those of you looking for a change in venue, or for those of
you looking for Asterisk-clued admins and developers.  (watch this
space for more details)

In fact, it looks like AstriCon is situated to be among the biggest shows for the quarter in the … Continued

Giving and Taking

First of all, I’d like to wish everyone a Merry Christmas (well at least to those who celebrate it and/or appreciate the sentiment)! It’s a day when many people, myself included, put an especially significant thought into giving. What many people do during Christmas is give gifts (perhaps in recognition the gift that many Christians celebrate receiving 2000+ years ago).

In the early days of Asterisk, when I went to conferences and sat on stage with folks from Cisco and Avaya and other big telecom vendors, they tended to look at Digium like a charity, and Asterisk as purely a … Continued

Spreading the Word, not just the Code

You know, I didn’t really start out on a mission to change the world, but more just seemed to stumble into it. When I started Digium (Linux Support Services at the time), it was just me. The mission was really about seeing what I could do. Then you start to add some people and it’s about what “we” can do. Before you know it though, there are so many people involved and then this whole world of people who have become involved with Asterisk both in terms of using it and developing for it and even businesses springing up all … Continued
