Hi Ben, I am looking for a tool like wireshark to decrypt the SRTP packets and listen to the audio. RTPengine as you said we can bridge two channels and we can't use it as a tool for decrypting SRTP traffic, Regards On Fri, Oct 31, 2014 at 7:25 PM, Carlos Ruiz Díaz <carlos.ruizdiaz@gmail.com

I understand that this is not what he is intending. Why would he need yet another rtp bridge if FS already does exactly that. On Oct 31, 2014 7:36 AM, "Ben Langfeld" <ben@langfeld.co.uk> wrote:
The way I use rtpengine, it rewrites SDP between the browser and Asterisk 1.4, terminating DTLS and ICE. Between the browser and rtpengine is RTP/SAVPF, while between rtpengine and Asterisk is RTP/AVP. rtpengine generates its keys in what I assume to be the same way the browsers do.

The tool from pjsip mentioned above requires the keys for the srtp decryption. Does the one you mention do it differently?

Anthony, I think I'm not understanding your concern. Could you explain what you mean by logging the keys?

The bigger question is how to log the keys without compromising the point of why its all encrypted. It would take some careful consideration.

rtpengine does indeed allow decryption of DTLS encrypted RTP. I use it in front of Asterisk 1.4 for exactly that (and ICE resolution).
