[Freeswitch-users] Freeswitch webRTC - audio DTLS key err

I’ve deleted dtls-srtp.pem (and dtls-srtp.key) and restartet freeswitch.The file dtls-srtp.pem was regenerated and the error does not appear anymore :-). One other question, the certificate dtls-srtp.pem was generated, but not the private key file dtls-srtp.key. Where can I find it? 

Thanks

Markus

I’ve added my own cerificate and installed in /usr/local/freeswitch/certs. I’m connecting to freeswitch using JsSip library.  The signaling part works fine, I can see all SIP messages in the log, but then it fails to establish the audio/rtp connection:
