Hello all!
A few news items just crossed my desk and I thought you'd appreciate having some quick links. These all come from Channel Partners, so a quick tip o' the cap to them for sending these along:

  • SIP Trunking Reality Check - Some good things to keep in mind when buying (or installing) SIP trunks.
  • PBX Sales Are Growing Again - No surprise that Cisco (bleh) is the market leader, but there is a surprise entry on the list. (Sorry, it's not FreeSWITCH or CudaTel... yet!)
  • CenturyLink Keeps Growing - After completing its acquisition of Qwest, CenturyLink gobbled up Savvis and is now the third largest telecom in North America.

If you have other news picks feel free to send them my way or drop them into the comments section on this post.

Flex Client For mod_rtmp Now In Git!

Submitted by mcollins on Wed, 07/06/2011 - 17:02

Good news for for all of our RTMP users: Anthony has checked the sample Flex client into the main FreeSWITCH repo! This is essentially the same client that is used on the new FreeSWITCH conference interface.
The response to mod_rtmp has been exceedingly positive. While mod_rtmp covers the server side of things, many have asked for more information and ideas on what to do on the client side. The sample Flex client is a great starting point for prospective developers to learn more about building an RTMP client. 
In addition to the sample client, we also have a Jira case open for the building of a more complete RTMP client. We've had a good response to the call for volunteers to help. Most of them are willing QA testers, which is definitely a good thing. We have also had a few programmers with Adobe development experience volunteer to assist. If you are able to help out please add your name to the comments section on FS-3368.
Lastly, we'd like to remind everyone that you can learn more about mod_rtmp - not to mention rub elbows with the FreeSWITCH developers - at ClueCon 2011, which is being held in Chicago this August 9-11. We hope to see everyone there!

Tech News Items Relating To VoIP And Telecom

Submitted by mcollins on Thu, 06/23/2011 - 20:54

Today has been a bit busy with tech news that may be of interest to our community so I've summarized a few items and have provided links. They both come via Slashdot:
FCC Ups Penalties For Caller ID Spoofing - This is a good one to keep in mind if you are a service provider. Make sure that your users aren't up to no good - we'd hate to have our community members drawn into litigation because of illegal activities on the part of individual users. Note that modifying caller ID isn't the issue here, but rather "to commit fraud or with other harmful intent."
USPTO Rejects Many of Oracle's Android Claims - More good news from this proverbial clash of the tech titans. If you didn't already know, Oracle is suing Google for infringing on various Java-related patents that were acquired when they bought Sun Microsystems. It seems that most people realize just how silly these patents are - even the USPTO, who in their infinite wisdom issued the patents in the first place, has rejected many of the claims. If you want some deeper insights into this issue I highly recommend reading Groklaw's coverage of the litigation.

Announcing The First Truly Free RTMP Solution For Open Source VoIP!

Submitted by mcollins on Tue, 06/14/2011 - 23:54

The FreeSWITCH team is pleased to announce that we have officially released mod_rtmp - the first truly free RTMP solution for open source VoIP and telephony! A special thanks goes out to Barracuda Networks for sponsoring the professional development of this module and allowing it to be freely released under the MPL along with the rest of FreeSWITCH.

RTMP - the Real Time Messaging Protocol - was originally developed by Macromedia to allow the streaming of audio and video through the ubiquitous Flash player. After Adobe acquired Macromedia they released the RTMP specifications which has allowed third party developers to create server-side applications that work with Flash and other RTMP-enabled clients. mod_rtmp turns FreeSWITCH into an RTMP server, allowing you to bridge RTMP client streams to SIP and TDM connections as well as conferences. Currently, mod_rtmp supports the Speex audio codec.
One of the applications of this technology is to allow Web site visitors to make phone calls right from their browser. A company's Web page can detect Flash and offer the visitor an option to "Click Here" to speak to a customer service representative.
To illustrate the usefulness of mod_rtmp, Anthony Minessale has added a Flash-based connector to the public FreeSWITCH conference. Browse there and try it out. Be sure that Flash is installed for your browser and that you have a headset or other audio device. For security reasons you will need to explicitly allow Flash to access to your audio device. Click "Call FreeSWITCH Conference" and then enter a name in the popup box. Click "Call" and you will be connected to the FreeSWITCH public conference. (Be sure to open the keypad and press zero to unmute!) If others are present you will be able to speak with them. Audio devices that support wide-band audio will produce higher quality audio.
Would you like to learn more about FreeSWITCH and mod_rtmp? Be sure to join the FreeSWITCH developers at ClueCon 2011 this August 9-11 in Chicago. ClueCon is a great opportunity to meet the authors of some of your favorite open source VoIP and telephony software projects.
