G.729 Codec Licenses Now Available For FreeSWITCH!

Submitted by mcollins on Thu, 04/01/2010 - 23:34

The FreeSWITCH team is pleased to announce that users may now purchase licenses for the G.729 audio codec. Licenses are immediately available for FreeSWITCH systems running on Linux. Mac OSX and Windows systems will be supported soon. A single license includes one encoder and one decoder, which is suitable to handle one phone call.
 
G.729 is a toll-quality, low-bandwidth audio codec supported by many VoIP providers. The voice quality of a G.729-encoded call is about the same as that of G.711, the codec used for standard PSTN calls. However, the amount of bandwidth needed to carry a G.729 call is much lower than that for a G.711 call. Enterprises using G.729 will make more efficient use of available network bandwidth.
 

Interesting Blog From PersianAdmins

I just saw this interesting series of posts from "patris1" over at persianadmins.com. It discusses the "marriage" of FreeSWITCH and Speech Server 2007. The posts are all written in English, but it looks like the author is multilingual so if you know of any who speaks Farsi and is looking for other FreeSWITCHers to network in that language then this author would probably be a good resource.

Introduction to SIP Part Two

Submitted by mcollins on Tue, 03/30/2010 - 19:17

The folks over at Ars Technica have posted part two of a nice introduction to the SIP protocol. This series of articles is a pretty nice and gentle introduction to the protocol with which all seem to have a love/hate relationship. It's definitely worth a read, especially for those who are still a little new to VoIP and SIP.

Here's a provocative post up over at FierceVoIP suggesting that possibly Polycom and Siemens Enterprise will merge. Evidently Polycom is feeling the heat from "recent consolidation of its competitors." Curious, no?

Skype On Verizon - Wireless VoIP Is Here! Oh Wait, Never Mind...

This post is up over at FierceVoIP regarding "Skype on Verizon's network." Too bad it's Skype on the voice network and not on the data network. Oh well, maybe next time...

Congratulations to Brian West for having the honor of the 17000th SVN commit for the FreeSWITCH project! Development on the project continues to gain steam as the core developers (Anthony Minessale, Michael Jerris, and Brian K West) have been joined by a small but talented group of programmers like Mathieu Rene and Rupa Schomaker. The pace of commits has sped up over the past few years as these and others have joined the project.
 
We would like to say thanks to all those in the FreeSWITCH community who continue to support FreeSWITCH and open source.

FreeSWITCH In Action: Handling Thousands of IVR Calls

This interesting blog post came across the wire today. It's from a tech professional who needed a scalable solution to handle thousands of inbound and outbound calls with IVR capabilities. Those of us who have taken on challenges like his can appreciate the magnitude of the project and how difficult it can be to implement a viable solution. It sure sounds like he's happy with the solution he built around FreeSWITCH.

I thought this was a nice article over at Tech Crunch. (For those who don't know, TC does lots of articles on web startups and cool new technology stuff.) It discusses a cool project called PBWorks (formerly PBwiki) that uses FreeSWITCH to power the voice component. Check it out!
