Get G.729 Codec Licences For FreeSwitch

G.729 Codec Licences For FreeSWITCH http://snapvoip.blogspot.com
As anyone involved with VoIP IP Telephony know that G.729 codec is a toll-quality, low-bandwidth audio codec supported by almost every VoIP providers on the planet. The voice quality of a G.729-encoded call is similar to that of G.711, the codec used for standard PSTN calls. But there is a major diference in bandwidth  used, G.729 uses only one fourth of the bandwith G.711 uses.
G.
Codec...Sample_Rate...Bandwidth...NominalBandwidth...Payload....License
G.711......8(kHz).......64(kbps)......87.2(kbps)........20(ms)....OpenSource
G.729......8(kHz)........8kbps).......31.2(kbps).........20(ms)....Patented.

So anyone using G.729 will make more efficient use of available network bandwidth. Basically making three G.739 calls using the same bandwidth for a single G.711. Personally I like the 48K CELT Codec on FreeSWITCH .
Just like G.729 for Asterisk (hardware cards) licenses are available at $10 per channel for FreeSWITCH systems running on Linux. Mac OSX and Windows systems support are forthcoming..
Just click on the g729 tab on main FreeSWITCH page.

FreeSwitch 1.0.2 Released

http://snapvoip.blogspot.com/


The FreeSwitch team has released a new version of FreeSwitch to celebrate the new year. The release comes with a bunch of new fixes and features. Most notables are the benefits of teaming with Polycom. FreeSWITCH team has made it extremely easy and simple to reach into Polycom's wideband (WB) and ultra-wideband (UWB) Siren(tm) family of codecs. This is a very important milestone as many commercial, SMB and SMEs use polycom equipment within their networks.

Another exciting development which we wrote about earlier (48k CD Quality VoIP with CELT), is the addition of the 100% open-source CELT codec. CELT supports sampling rates higher than the 44.1kHz rate used by traditional CDs.
To prove the value of the CELT codec, FreeSwitch members Anthony and Brian played/listened to a guitar solo over a 48kHz session via FreeSwitch and Celt. The listener, Brian has summed it up as awsome!.
These are very valuable codecs to VoIP Users and VoIP Developers. About 6 years ago, I helped to develop a VoIP Telephony system based H323 Gatekeeper and G729 codec. The licence fee for G729 almost stopped the project in its tracks.
With these codecs people will be able to conduct HD quality conferences over VoIP. Whether over private or public networks, the use of WB Telephony, UWB Telephony, and HD telephony will reach very high denominations, provided that you use technologies like FreeSwitch and CELT.
There is more. Another two most notable features added are the FreeSwitch fax capability and a FreeSWITCH remote client. Thanks to the fax capabilities, dialplans now can be used to route inbound or outbound fax calls.
The Remote client is capable of connecting to local or remote instances of FreeSWITCH. An INI-style configuration file allows for multiple profiles. Think Administrates handling multiple FreeSwitch instances!
There are many more items to list and the changelog list 290 of such items. So read this article about the release and then install the new version!
Thank you FreeSwitch Team!

48k CD Quality VoIP with CELT, Another First From FreeSwitch!

http://snapvoip.blogspot.com/


FreeSwitch has started supporting CELT, a new open source audio codec that allows for CD-quality voice and sound transmission. This certainly a boost for VoIP World. CELT is an "ultra-low delay" audio codec that supports both voice and music and said to carry 48kHz VoIP in 48kbps of bandwidth. Compare that to PCM mu-law codec, G.711u, which consumes 64kbps of bandwidth to carry 8kHz audio!
I have not yet tested the codec but plan to integrate the mod_celt and the new FreeSwitch client very soon in my testing rig. Main while, you can find more information at FreeSwitch Post and the following links.

For more information on CELT please visit the project home page and for more information on other free codecs please visit the Xiph page.
