Hi, I suppose, it happens for real connections, too. But since it's so sporadically, I guess, clients just retry and then it works.
The operating system is an Ubuntu 18.04 (getting replaced by Ubuntu 20.04 soon), thus it's running with libssl 1.1.1.

Or also for the connections tried from the usual sip phones? What is the operating system and libssl version?
