[svn-commits] mmichelson: branch 1.4 r129436 - /branches/1.4/main/rtp.c

[SVN commits to the Digium repositories]

Author: mmichelson

New Revision: 129436

URL: http://svn.digium.com/view/asterisk?view=rev&rev=129436
Log:
Fix a problem where inbound rfc2833 audio would be sent to the 
core instead of being P2P bridged. When the core regenerated
the rfc2833 packet for the outbound leg, the SSRC would be different
than the RTP audio on the call leg causing DTMF detection issues on
the far end.

(closes issue #12955)
