New Revision: 378218

URL: http://svnview.digium.com/svn/asterisk?view=rev&rev=378218
Log:
Ensure chan_sip rejects encrypted streams without crypto info

This ensures that Asterisk rejects encrypted media streams (RTP/SAVP
audio and video) that are missing cryptographic keys and ensures that
the incoming SDP is consistent with RFC4568 as far as having a crypto
attribute present for any SAVP streams.
