[Asterisk-Users] SRTP: followup

[John Todd]

I have found few VoIP clients that support encryption.  The only one 
that comes to mind is the Zultys devices (they have a softphone and a 
hardphone that support SRTP.)  I spoke with them as recently as 
today, asking if they'd be interested in supplying patches for their 
AES-based SRTP encryption implementation to Asterisk, and they said 
that they didn't have the ability to put those patches together at 
the moment, but they'd be happy testing functionality with their 
devices and Asterisk once implemented.

Has anyone done any work with SRTP and Asterisk that could become 
public?  I've still got a number of clients who aren't moving towards 
VoIP due to security concerns with end-user stations.  There are now 
quite a few AES-specific files stuffed into the Asterisk 
distribution, and a quick "grep" doesn't show anything using them. 
Hopefully this means that we're almost at the edge of making SRTP a 
reality...
