[OpenSIPS-Users] rtp_proxy_stream2uac and opensips-1.6.4

[Flavio Goncalves]

Hi Kamen,

Thanks for the indication, I found this in the source code of makeann.c

+then
+  echo "***************************************************************************
$ECHO_C" 1>&6
+  echo "* Please contact sales at sippysoft.com
 if you need G.729 support in makeann * $ECHO_C" 1>&6
+  echo "***************************************************************************
$ECHO_C" 1>&6

I've sent an email, probably there is a fee for the codec.
