Watch Out For May 5 - Calls Might Fail!

Here is an interesting heads up from Slashdot: On May 5, at 17:00 UTC, DNSSEC will be rolled out across all 13 root servers. Chances of this going smoothly and not affecting anyone is pretty small. So be prepared! Oh, and if your phones stop working don't call us! Not that you could anyway...
 
Be sure to check the test site if you have any questions about DNS and your networks.

Many of us have been around FreeSWITCH for a number of years. Like you, I've lost count of how many times someone has asked, "Is there a GUI for FreeSWITCH?" There have been several projects started, all of which are in various stages of development. One project of particular note is FreePBX Version 3. Now the guys over at Chillingsilence have put up a nice little step-by-step tutorial on getting FreePBX V3 up and running with a LiveCD. It's a good read, especially for anyone who is interested in learning more about the current state of FreePBX V3 with FreeSWITCH as the telephony engine.

Be Careful When Deploying a "Cheap" VoIP Solution

Submitted by mcollins on Thu, 04/08/2010 - 17:29

I thought this story would be of interest to those who work in the VoIP field. It's about a small company who wanted to save money by going VoIP. They chose Asterisk because "it's cheap" and they wanted to implement it themselves to save even more. Their in-house IT staffers had trouble keeping the system stable. Many FreeSWITCH users are familiar with Asterisk instability issues - indeed they are using FreeSWITCH because of such issues. However there are other things to be gleaned from this example.

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.
