Hi, Richard!
Thank you for quick feedback!
There is no such attribute in SDP payload from the latest Mozilla (v.29).

But it presents in SDP from Chrome (v.34)

No success for both browsers. It's should be noticed that Chrome provides both SDES ("crypto") and DTLS ("fingerprint"+"setup:actpass") attibutes (does DTLS have priority in a such case?). However rtpengine doesn't provide such SRTP data. May be any suggestions?
kind regards, Alexey

Hi,
Can you check if the original offer contains an "a=setup:actpass" attribute? I remember Firefox having a problem with this in some version. This attribute is required for DTLS-SRTP and Firefox was not sending it. It's fixed in later versions.
cheers
