Hello Gregor,I have upgraded the openssl version to 1.1.0e from the following link. But the issue remains the same.http://slproweb.com/download/Win64OpenSSL-1_1_0e.exeIs the above way correct to upgrade the open ssl.Thanks and Regards,SachinFrom: Brian West <brian@freeswitch.org>Sent: Fri, 05 May 2017 19:26:58To: FreeSWITCH Users Help <freeswitch-users@lists.freeswitch.org>Subject: Re: [Freeswitch-users] Changing audio DTLS state from HANDSHAKE to FAIL issue Clearly that isn't the case, I suspect a define is missing to actually enable ECDSA at this point.

I am using windows. I had this error when client was Chrome. I just updated openssl dlls. I think that openssl library is updated on windows build now with version 1.6.17. And this version is also compiled on FS FTP to just download and install it. 2017-05-04 19:15 GMT+02:00 Anthony Minessale <anthony.minessale@gmail.com>: FS 1.5 sounds like a bad plan.Try latest FS 1.6 or master.
