A belated happy new week to you all!

As Ken mentioned in his email yesterday, the big news from last week is, of course, the release of FreeSWITCH 1.2.9 stable. This is now the "latest stable" version of FreeSWITCH and the one most recommended for production use. The tarball is available from theusual location. The CentOS and Debian packages have also been updated to use the latest stable. 

On last week's conference call we welcomed Dan from the CGRateS project. CGRateS is a relatively new project that handles call rating for carrier-grade operations. We are happy to have CGRateS (an open-source project itself) as part of the FreeSWITCH ecosystem.

On this week's call we look at another VoIP-related OSS project: This software performs a number of monitoring functions for VoIP implementations. Please join us tomorrow at 1PM EDT, 10AM PDT for an interesting discussion. 

One ClueCon reminder: We are still accepting speaking proposals, however time is running out so please send them in as soon as possible. We hope to have the ClueCon 2013 schedule released in the next few weeks.

Take care and have a great week!

Happy first May Monday to all.

We are please to let everyone know that the new FreeSWITCH book is nearing completion. Each day the Packt editors have been sending us revised and re-revised chapters to polish off. If we keep up our current pace then it is quite likely the book will be available in early June. We hope you enjoy it.

On last week's call we enjoyed a nice presentation from Omar over at OrecX who showed us some of the useful features of their call recording
solutions. They have an open source version as well as commercial versions. If you are looking for a call recording solution then we recommend that you review what OrecX has to offer.

This week we continue in our series of presentations on FreeSWITCH-compatible software applications. We look forward to having Dan Bogos from CGRateS join us to talk about their project. Click here to get a quick look at what CGRateS does, and then make plans to join our call on Wednesday.
Regarding ClueCon 2013 we would like to remind everyone that we are still accepting talk proposals. If you have a talk idea please let us know. In the meantime feel free to get registered and book your hotel room at the Hyatt.

Have a great week!

Hello Friends,
We are looking forward to a busy but good week of activity. Last week was busy as well. On last week's conference call we had an engineer from JeraSoft join us to answer some questions about the newly released VCS 3.4.2. We are happy to have this new version as part of the FreeSWITCH ecosystem.

This week we welcome Omar from OrecX. OrecX creates commercial and open source telephony recording solutions. We look forward to learning more about how we can use OrecX with FreeSWITCH.

One other bit of good news: All of the content for the new FreeSWITCH book has been submitted to the publishers. We are doing a bit of editing on one of the chapters but otherwise we are basically done. We anticipate a
June release.

Take care and have another fantastic week!

The FreeSWITCH team is pleased to announce that we have another product in our ecosystem: JeraSoft VCS version 3.4.2. The JeraSoft official announcement and official release notes can be found here.

  • RADIUS authentication of customers
  • RADIUS authorization of calls (including balance limits)
  • RADIUS start/stop accounting
  • Dynamic routing via SIP redirect server

Feel free to visit JeraSoft to learn more about how to use this software with your FreeSWITCH implementation.

Happy tax day to those in the USA - we hope all is well with your business. Speaking of business, I thought I would relay the interesting news about Dish Network making a bid for Sprint. Many here in North America will be keeping a close eye on this one. Whether or not this is just a big mess or an opportunity for Sprint to become a "real" competitor to AT&T and Verizon remains to be seen. Regardless of the outcome, most of us here are hoping for a healthier Sprint so that we can avoid another duopoly.

On last week's conference call we decided to have a preliminary discussion so that we can prepare for this week. Dave Kompel will be showing us how to build rapidly FreeSWITCH applications in MS Visual Studio 2012 and have those run under mod_managed. Be sure to consult this document so that you can get all the rerequisites installed in time for our call on Wednesday.

In other news I would like to let everyone know that I spoke with Kashif Kahn over at Vestec. We are gearing up for the automatic speech recognition application building contest. The winners will be announced at ClueCon 2013. The official contest page will be posted on the ClueCon website shortly. Stay tuned for more information and be ready to start building your ASR applications!

The ClueCon 2013 call for speakers recently went out and we've had a number of submissions already. We look forwarding to hearing more talk ideas, so please send those in right away. In the meantime ClueCon registration is now open so be sure to get signed up, and don't forget to book your room at the Hyatt Chicago Magnificent Mile hotel for only $169 per night.

New Improvements for April

Submitted by anthm on Mon, 04/01/2013 - 18:28

Since its spring, we decided to mess up up our tree by adding a bunch of new code overnight.  We added all kinds of new standards and media processing code because, hey why not!  
We also addeed new lossless audio codec.  mod_b64.  It actually preserves 100% of the original audio signal by seamlessly transmiting the stream as rot-13-encrypted-base-64-encoded-audio in regular and high def!  Add that to the list of many FS firsts!  At this rate we probably even support webICEE or Big gulp  or whatever they call that fancy new stuff.  
What'll they think of next? !!!

Introducing FeeSWITCH

Submitted by anthm on Mon, 04/01/2013 - 16:06

Welcome to FeeSWITCH, the worlds first fee-driven open source project!
In order to use FeeSWITCH you simply download the code and build it and use paypal to send donations to paypal via the button on the right of the page.  The fee can be of any size though we prefer hefty fees over light fees.  We prefer that you pay the fee as often as possible.  The more often you pay the fee, the better your calls will sound especially if you purchase the new FeeSWITCH ultra gold plated VoIP-Ready voice-enabled ethernet cables from the same guys who brought you Monster TV cables and Beats headphones.

Are Freeloaders Necessary for FOSS Success? Maybe So!

Submitted by mcollins on Thu, 03/14/2013 - 00:12

From Slashdot comes this interesting read about the math of FOSS projects. Whether you agree or disagree I think you'll enjoy the story.
Let us know what you think: are so-called freeloaders ultimately good for a successful FOSS project?
