Hello,

I am testing mediaproxy-ng (running on CentOS 6 on Amazon EC2) for
WebRTC to non-WebRTC calls and I am getting one-way audio most (but not
all) of the time.

I always get audio in the WebRTC to non-WebRTC direction.

Has anybody had any experience of anything this?

I have checked the obvious (all the ports open in iptables and the
Amazon security groups).  I know that the right (advertised) address is
going into the SDP.

I am getting an error message out of mediaproxy-ng a lot.  But it is
there whether the audio works or not.  The error I am seeing is: "Error
generating SRTP session keys".

Can you post a complete log excerpt, particularly including the SDP bodies? Maybe even one for each case (working vs non working)

cheers
