[SVN commits to the Asterisk project]

New Revision: 380043

URL: http://svnview.digium.com/svn/asterisk?view=rev&rev=380043
Log:
Corrected crypto tag in SDP ANSWER for SRTP.

When Asterisk responds with an SDP ANSWER for SRTP, it had the code to
correctly fill in the cryot data, which was overwritten by a call to
sdb_crypto_offer. Corrected the situation by changing sdp_crypto_offer
to not replacing crypto data if it already exists.

(closes issue ASTERISK-20849)
