<pre style="white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">See above about conversion functions. Also, the only places I see this called specify the type in the call--is there any reason we don't just pass the AST_ version to the function instead of the PJ_ and do away with conversion altogether?</pre>

<pre style="margin-left: 1em; white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">Ah, missed the call to pj_ice_calc_foundation above. So perhaps just always passing things around as the AST_ version, then have a conversion function for when we need the PJ?</pre>

<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 support for the following:
ICE attribute parsing and generation in chan_sip
Usage of the ICE interface in chan_sip
ICE support within res_rtp_asterisk
STUN support within res_rtp_asterisk for getting the server reflexive address
TURN support within res_rtp_asterisk for relaying traffic when needed
Additional configuration options for the above
One area which could use some feedback is the pjproject integration. Should we try to use their build system as I have done to integrate things, or try to roll their stuff into ours further?
If you would like some background on ICE and the actual support here take a gander at the wiki page located at https://wiki.asterisk.org/wiki/display/~jcolp/ICE%2C+STUN%2C+and+TURN+Support - hopefully it proves useful to you.</pre>
