Hi,I did my tests with Jitsi soft phone too that support SRTP. But the situation not has been changed.I'll crazy.

I think it will not work.You must use SRTP, or modify my config.

I don't see force SRTP option,I set it to Prefer SRTP. I did this like your pdf attachment.

Hi,Thanks. I see.Have you any idea about this error : "SRTP output wanted, but no crypto suite was negotiated" ???Is this related to dtls handshake and fingerprints?I see this too: https://github.com/sipwise/mediaproxy-ng/blob/master/daemon/rtp.c
