Hi Med, Happy Eyeballs worked fine with me with the Call Home DOTS server initiating the DTLS and TLS sessions. Heartbeats work, but I have not tested them under stress / loss conditions. I will try to get that tested tomorrow. In terms of the text I mis-read, perhaps it could be partially re-written OLD " If TCP is used, the Call Home DOTS server begins by initiating a TCP connection to the Call Home DOTS client. Using this TCP connection, the Call Home DOTS server initiates a TLS connection to the Call Home DOTS client." NEW " If TCP is used, the Call Home DOTS server begins by initiating a TCP connection to the Call Home DOTS client. Once connected, the Call Home DOTS server continues to initiate a TLS connection to the Call Home DOTS client."
