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

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
