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.

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!

Acquisition Complete: Skype Now Part of Microsoft

Submitted by mcollins on Fri, 10/14/2011 - 18:05

Our buddy Dan York has written a piece about Microsoft's assimilation acquisition of Skype. For better or for worse it is a done deal. I don't know about you but I must confess that I'm keeping my eye on this one. It could be great or it could be a train wreck. In either case I've got the popcorn ready...

Idiocy In Action: Astrologers Claim Copyright on Timezone Data

Submitted by mcollins on Fri, 10/07/2011 - 22:43

Those of you running Linux/Unix systems no doubt make use of the time zone database. Now it seems a foolish group of astrologers/software developers has actually sued the long-time maintainer of this database, among others. They claim that they have a copyright on the timezone data. All the selacious details are available in this Techdirt post. Keep your eyes open on this one, it should be interesting.

Bugger Off: Spying Online is Perilous and Unneccessary

An interesting item just came across my desk. A post over at Boston Review talk's about Susan Landau's new book: Surveillance or Security?: The Risks Imposed by New Wiretapping Technologies. It is quite an interesting read. If you are at all interested in Internet security and privacy, especially with VoIP communications, I highly recommend reading this article
