<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;">This is the way that chan_sip currently behaves for encryption=no as I understand the code (it's entirely possible that I read it wrong). Are you saying we want to drop the behavior I've specified for "no" and replace it with the behavior I've specified for "deny"?</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;">Add support for SDES SRTP in chan_gulp/res_sip. Available options for media encryption for a given endpoint are deny (no encryption allowed), no (none offered by default, but silent upgrade to SDES allowed), and sdes. This also supports mid-call rekeying as far as I could test it. Much of the code necessary for this functionality was factored out of chan_sip or pulled from channels/sip/.</pre>
