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!

FreeSWITCH Continues to Grow as JeraSoft Releases VCS 3.4.2

Submitted by mcollins on Mon, 04/29/2013 - 17:25

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.
For those who may not know, JeraSoft VCS is a routing and billing solution that works with a number of VoIP platforms. Since FreeSWITCH continues to grow as a carrier/provider solution it is good for those using it as such to have such an option. Some highlights of the new release are:

  • 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.

FreeSWITCH Weekly News and Notes

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.

Have a great week!

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

Let us know what you think: are so-called freeloaders ultimately good for a successful FOSS project?

Interesting Patent News: MPEG-LA Provides Google with Royalty Free License to Patents in VP8 Codec

Submitted by mcollins on Fri, 03/08/2013 - 02:35

Via Slashdot comes this encouraging story about MPEG-LA giving a royalty-free license for all patents that may apply to the VP8 video codec. The official announcement can be found here.
This is an important step for the VP8 codec. MPEG-LA handles the licensing of patents for many patent holders. By acquiring the rights to these patents - and on a royalty-free basis, Google can be much more confident that VP8 can be put into production without concerns about patent litigation. Of course, there may be individual patent holders (or patent trolls) out there who may feel that their patents are infringed by VP8. Time will tell if those with other patents will come forward, but this is good news for Google none-the-less.

* Do Kiosks and IVRs Threaten Human Interaction - This is an interesting article about how many of us prefer not to interact with a human under many circumstances.
Enjoy the articles and be sure to send along any VoIP/Telecom news items you'd like to share.
