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

Presence with Asterisk

Presence is one of my favorite features and is entirely possible with Asterisk+Bluetooth. Presence is the ability for the IP PBX to recognize when someone's in or out of the office. When you're in the office, the IP PBX will route calls to your desk phone, and when you'… Continue

Garrett Smith on SIP Trunking & Packet8

Garrett Smith is right on the money in his appraisal of Packet8's new SIP trunking service. I wonder if anyone sees the paradox in this? A year ago when I was shopping around for a hosted IP-PBX I looked at Packet8, but they didn't make the cut. One of the major reasons I couldn't consider them is that their business class service relied upon an ATA and an analog phone. Apparently it still does. We had a requirement for SIP hard phones in a variety of locations. This also begs the question, "w… Continue

Asterisk Where You Least Expect it

I'm on-the-road again the next few weeks. This week I have meetings in Burlington VT. That's just about as far from Houston as you can get up the East coast. The pity is that the northeast has been having Houston style weather, hot & humid. I had hoped from something of a break from it during my travels. As I travel I amuse myself by listening to podcasts. This week I'm contributing as well. I'm part of a group of volunteers that have stepped up to help Dan York & Jonathan Zar with audi… Continue

External Paging with Asterisk

In the spirit of exploring the capabilities of Asterisk beyond its typical use as an IP PBX, external paging is a great feature to increase the value of your Asterisk system by having it assume the functionality typically reserved for a distinctly separate system and additional investment.

Botanicalls - use Asterisk to water your plants!

One of the things I want to do with this blog is explore all the wild applications in which Asterisk is being used under-the-hood. Rarely do people advertise the use of Asterisk in their VoIP products so here's one business where Asterisk was just right for a very unique application. Although they've been around for over a year, Botanicalls have designed a product that lets your home plants call you whenever it gets parched or has something to say. Sounds crazy but completely true... and a bril… Continue

VoIP, QoS and MPLS ... Wanna buy a bridge?

John, Jane and George work at the Empire State Building in New York City, they each leave work at 5PM and are always in a rush to get home. One day while rushing to get home, all three individuals rush into the revolving door, they're now jammed into the door. On the way out, they can only exit one person at a time. To alleviate this problem, the building's owner decided to place a doorman in the lobby to direct traffic out the door in order to avoid having that congestion. He decided it would b… Continue

Mikey phone home..

In the Hollywood movies when the hero has to construct some communication solution they're either working in the confines of a submarine, trying to make a PC based communication system work to confirm launch orders, or it's a jerry built system based on a, umbrella, a speak N spell and a circular saw blade. They're either exceptionally well made, or very badly made. We're lucky.. we have Asterisk. Last year or so, I attended a course in Birmingham about the joys of VOIP. Since then I have been… Continue

Get to know SIP if you haven't already

I still find it surprising the number of IT directors and CIO's who still have no idea what SIP is. This is mostly the case with SMB businesses but even if you're a small multi-site organization, you're not doing anyone justice by ignoring new technologies. Because I run into so many people who don't have a solid grasp of what SIP can do, I wanted to write a post laying out some examples. So what is SIP? Only the greatest communications protocol in the world! Go… Continue

Sangoma releases new FlexBRI card - hybrid analog/digital card

Sangoma states that this new card "will support synchronous clocking on all channels for 100% guaranteed error-free faxing." I like the sound of error free faxing!

Asterisk & Microsoft Office Communications Server 2007 integration

Deploying a phone system is one thing... getting users comfortable is another...

fring™ - a mobile VoIP client with SIP... among other things

Almost halfway through 2008 and already we're seeing Asterisk everywhere. Asterisk has permeated almost every market in which VoIP is used, from the small business market to the carrier space. The question is, where is Asterisk going to pull ahead in 2008 and in what market?… Continue
