/* FreeSWITCH does not correctly handle an H.323 subtely, that is that a
MAXIMUM audio frames per packet is nototiated, and there is no
requirement for the remote to actually send that many. So, in say GSM, we
negotiate up to 3 frames or 60ms of data and the remote actually sends one
(20ms) frame per packet. Perfectly legal but blows up the media handling
in FS.
#define CF_NEED_FLUSH (1 << 1)
struct mod_opal_globals mod_opal_globals = { 0 };
Eventually we will get around to bundling the packets, but not yet. This
compile flag will just force one frame/packet for all audio codecs.
