Status
------

This change has been marked as submitted.


Review request for Asterisk Developers.


Bugs: ASTERISK-21416
    https://issues.asterisk.org/jira/browse/ASTERISK-21416


Repository: Asterisk


Description
-------

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/.

Testing
-------

Hand testing with several SRTP-capable endpoints and mid-call rekeying tested with minor tweaks to an otherwise unmodified chan_sip.


Thanks,
