For what it's worth I have a howto written up about setting up asterisk
with SRTP etc...

http://www.e164.org/wiki/AsteriskSRTP

Thanks. But how is a common session key established in this case? If it is randomly generated and transmitted in cleartext in the SDP content, as it appears from http://bugs.digium.com/view.php?id=5413 (use of "a=crypto .... inline:....), then the method only makes sense with SIP-over-TLS.
