Hans -
   SRTP is one of the projects that has been languishing for years  
with Asterisk (heck, I tested it with static keys back in 2005.)   
There now exists code with an appropriate license in the issue  
tracker, but the complexity of the patch set is fairly significant.  I  
would VERY MUCH welcome a review by a few people who have a good  
coding clue and some time.  It is my intention to see if Digium can  
put resources to getting it implemented, since I think that security  
is an underrated problem set (Hello, broken GSM encryption!) and we  
should get Asterisk up the point where SRTP becomes a "default" for  
new devices.

  The SRTP patch set:  https://issues.asterisk.org/view.php?id=5413

  PS: Is cryptcall.com selling/distributing Asterisk with SRTP?  We'd  
very much like to have them contribute back to the community with  
their code and experiences.  Their website is quite unfriendly.  How  
did you learn of their use of Asterisk?
