[Freeswitch-users] RTMP + G.729 Codec

Hi,

I am also trying RTMP calls. I am using the Flex calling to Nunace MRCP 
server for speech recognitions.
The same setup works well via the VoIP phone calls but not works via a 
web browser calls (via adobe Flex).
I notice there are a lot of "audio queue overflow" debugging outputs 
when calling via the Flex

I am wondering if any body has ever tried and get it working?

Thanks!

Xing
