<pre style="margin: 0; padding: 0; white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">This patch adds the following:
(1) A new module, res_hep, which implements a generic packet capture agent for the Homer Encapsulation Protocol (HEP) version 3. Note that this code is heavily based on a patch provided by Alexandr Dubovikov; I basically just wrapped it up, added configuration via the configuration framework, and threw in a taskprocessor.
(2) A new module, res_hep_pjsip, which performs packet capturing for the PJSIP SIP stack. This is one of those modules that I think really showcases how nice the new stack is - we're able to add a new module that inserts itself into the stack and forwards the message traffic off to the res_hep module without modifying the core parts of the stack itself. This means a system administrator could load this at will on certain Asterisk systems and - if the capturing isn't needed - unload it and keep the stack 'slim'.
A few notes:
* This code exists in the following branch:
http://svn.asterisk.org/svn/asterisk/team/mjordan/12-hep
* The code in the branch also contains a module for RTCP. While that actually *does* send RTCP information over HEP, it does so as a JSON blob, which is not super useful. It's an open question as to what the formatting should be, i.e., a SNOM-esque encoding, RFC 6035, etc. I'm open to suggestions on this, which is why I deferred that functionality for a later review.
* Much thanks to Alexandr for his Asterisk patch for this code and for a *lot* of patience waiting for me to port it to 12/trunk. Due to some dithering on my part, this has taken the better part of a year to port forward (I still blame CDRs for the delay).</pre>

This admittedly needs some *real* testing, as I have yet to stand up Kamailio with HEP. I think the code is far enough along to get some eyes on it however.</pre>
