Terrorist Group Supported By Hacked PBXes

We talk about security a lot around here, but this scary story from Ars Technica is a classic example of the worst-case scenario: bad guys hack into customer PBXes and really bad guys benefit from it. Definitely read this story and then go make sure you and your customers are locked down.

Newfies: A New Open Source Dialer Powered By FreeSWITCH

Submitted by mcollins on Wed, 11/30/2011 - 06:51
::

We love to hear stories about people building new and interesting things with FreeSWITCH. Community member Areski has done just that! Last week the Newfies-Dialer project announced that they have officially released version 1.0 of their software. I briefly spoke with Areski who gives us some details about the project:

 

Newfies-Dialer [is] a FOSS Voice Broadcast application ... built from Django, RabbitMQ, Celery, Plivo and of course, FreeSWITCH.

The project consists of a multi-tenant auto dialer system to enable the automated delivery of interactive phone calls to contacts, clients and the general public to develop and build applications and services for telemarketing, mass emergency broadcasting, phone polling, surveys and voting.

The architecture has been designed to be scalable, using distributed message passing to make make millions of calls per day via multiple cloud based instances of FreeSWITCH.

 

To learn more, visit the Newfies-Dialer website.

They're Here: The First Batch of ClueCon 2011 Videos is Online!

Submitted by mcollins on Mon, 11/28/2011 - 23:27

In case you hadn't heard already, we've posted a torrent with a large number of the ClueCon 2011 videos. In fact, we've created an entirely new site dedicated delivering large content like this: torrents.freeswitch.org. The current batch of videos is "standard definition" hence the torrent name of ClueCon2011-SD.torrent. Note that we had issues with one of our cameras so a few videos are not yet available - we will keep everyone updated.
 
Go grab the videos and check them out - we had some great speakers this year and you'll enjoy seeing their presentations.

Unlimited Mobile Data and Voice for $19/month - Too Good to Be True? Probably

Submitted by mcollins on Wed, 11/23/2011 - 20:35
::

I just saw this news item from The Register and I thought you all might be interested. It's a story about how Republic Wireless is going to be offering unlimited voice and data for $19 per month. Naturally, there is a catch: the phone will "seamlessly" piggyback on any open WiFi network to which it has access, including open WiFi hotspots. Supposedly this all happens in the background without any user intervention. I'm very curious to see if this actually works or not. Furthermore, how long before AT&T WiFi starts blocking these calls? We'll have to wait and see.

CenturyLink DSL Users Be Warned: Data Caps Are Coming

Submitted by mcollins on Wed, 11/23/2011 - 19:55
::

We've all heard of CenturyLink by now, and I'm sure some of you may not exactly be big fans. This story from Fierce Telecom will do nothing to change that perception. DSL users can start expecting data caps, either 150GB or 250GB per month, depending on the speed of the connection. If you have CenturyLink DSL and you use it for VoIP or other data-hungry apps then be on the lookout for their new "EUP" - Excessive Use Policy. On a brighter note, at least they aren't being like AT&T and charging extra right off the bat. Instead, those who go over will receive a phone call or email notification, most likely trying to upsell them to a new plan.

"There's No Such Thing As VoIP" - An Interesting Read

Submitted by mcollins on Mon, 10/31/2011 - 21:53
::

This item just came across my desk. It's a TMCNet article written by a guest contributor, Fred Goldstein. In it he discusses the chaotic mess that is the state of VoIP regulation here in the USA. This article is a good read for anyone doing any kind of VoIP business in the United States. I highly recommend it.

Nice Blog Post At GenesysGuru.com: Using FreeSWITCH to Secure VoIP Calls

Submitted by mcollins on Fri, 10/28/2011 - 18:35

I must confess that I had never heard of Genesys Labs until I read this blog post today. In any case, the author of the blog post has some nice things to say about FreeSWITCH, although I was more interested in his thoughts on setting up secure VoIP. His comments on setting up TLS and dealing with the challenges of certificates and CA's was pretty insightful. If you are thinking about doing TLS and/or SRTP then definitely check out this blog post - it is a good read.

Over at Astricon this story came out: someone got NAILED for $400K in fraudulent toll charges. Ouch, indeed! Remember the mantra: lock down your VoIP systems!

OnSIP Blog: Creating FreeSWITCH IVRs With JavaScript

Submitted by mcollins on Tue, 10/25/2011 - 16:41
::

I confess that when it comes to dialplan scripting I am partial to Lua. (After I all, I wrote chapter 7 of the FreeSWITCH "bridge" book.) However, some prefer the syntax of JavaScript. To each his own, and in that vein I thought I would share this blog entry from Mihail over at OnSIP. He discusses some of his challenges with creating IVRs using JavaScript and how he overcame those. If you like IVRs or JavaScript then check it out.
 
Note: OnSIP was a silver sponsor at ClueCon 2011. They are great folks and we're glad to have them in the FreeSWITCH community!

Oops: Finding Out The Hard Way That Your VoIP System Is Insecure

Submitted by mcollins on Mon, 10/24/2011 - 19:48
::

This story comes from David Rowe, VoIP hacker extraordinaire. This is a reminder that even the best of us can make mistakes and otherwise forget to plug holes that we already know about. I recommend you read up on his experience. It shows that a combination of factors - in this case a characteristically evil SIP ALG and a config file miscue - can conspire to make your system quite hackable. 
 
Let's all be careful out there!
