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".
Regards,
Peter

Can you post a complete log excerpt, particularly including the SDP bodies? Maybe even one for each case (working vs non working)
cheers
Hello,
I think (but I need to do more testing) the one way audio was related to early media and some issues with the media gateway I am using (which was generating the early media). Removing the body from 18[03] responses (and converting 183 responses to 180) seems to have made the problem much better.
However, I am still getting lots of "Error generating SRTP session keys" and occasional "Error generating SRTCP session keys" errors for every call.
Here is the log output:

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

I think (but I need to do more testing) the one way audio was related to early media and some issues with the media gateway I am using (which was generating the early media). Removing the body from 18[03] responses (and converting 183 responses to 180) seems to have made the problem much better.
However, I am still getting lots of "Error generating SRTP session keys" and occasional "Error generating SRTCP session keys" errors for every call.
The early media would indeed be responsible for the error messages you see... SRTP uses asymmetric encryption keys, and the keys present in an SDP body are to be used for the sending direction. IOW, with an offer coming from an SRTP client which gets translated to a non-SRTP SDP, mediaproxy can receive early media on those streams, but won't have an SRTP encryption key for forwarding the media to the offerer, as the key would only be sent in the answer SDP. Thus, SRTP (at least when used through SDES) makes early media impossible.
However, that issue should resolve itself once the answer SDP goes through, after which mediaproxy will have SRTP encryption keys for both directions and the error should go away. Maybe there's a different issue around? A full pcap including the RTP might be helpful.
cheers
