Hi, I am using PJSIP2.7 with keying set to DTLS-SRTP to setup a call between 2 clients running on Raspberry Pi. The call is being established fine, but I see errors during the media session (and hear no sound). During the handshake: dtls0x7421bd58 SSL_read() error: version too low After dtls_media_start(): Error sending RTP: Invalid operation (PJ_EINVALIDOP) The openSSL version I am using is: 1.1.0h. I have tried configuring openssl by enabling/disabling sslv3 with no success. Any clue pointing me in the direction would be greatly appreciated. Thanks, Apoorva
