[Freeswitch-users] Week in Review Feb 23rd-Mar 01

Wed Mar 5 09:55:09 MSK 2014

Brian,

Check out a Freeswitch to Freeswitch SIP connection over TLS with sofia 
debug all 9, thanks to Travis' commit
d5760e0d6a05b7a13bdb044018b2334c69d6cfdf, you can see that Freeswitch is 
negotiating the signaling connection for SIP over AES-GCM as well. It is 
a cool Easter egg I found while practicing setting up secure VOIP. I've 
included some sample logs below.

Community,

Does anyone have any suggestions for Freeswitch related 
videos/screencast? I'm looking to set up some quickstart videos for 
Freeswitch on different platforms and some walkthroughs such as how to 
report a bug on Jira, etc.

Freeswitch logs of a Freeswitch <=> Freeswitch TLS version 1.2 
connection register packet:

These last two platforms do require more work but I’m waiting on pending work from Mike Jerris on moving all mods to autoconf/automake which will make those last two platforms easier to support.  As we work on our build system on the unix platforms I suspect all these things will get easier to support.

>> Hello, again. This week in the FreeSWITCH master branch we had 137 commits! That is an average of ten commits per day and roughly an average of one commit every hour over the entire week! Awesome! We had a neat new feature added with TLS and SRTP support for AES-GCM. This feature allows for fully encrypting calls(both signaling, and media) in a higher density and with latest TLS 1.2 so it's secure against some of the recent TLS security issues. More about this new feature can be found here on the wiki: http://en.wikipedia.org/wiki/Galois/Counter_Mode
