Author: mmichelson
Date: Wed Sep  5 11:04:40 2012
New Revision: 372311

URL: http://svnview.digium.com/svn/asterisk?view=rev&rev=372311
Log:
Re-fix sending unnegotiated payloads during a P2P RTP bridge.

The previous fix still would look in the static_RTP_PT table, which
is inappropriate since we specifically want to find a codec that has
been negotiated.

(closes issue ASTERISK-20296)
