Hello,

for libssl/openssl v3.x, you have to use latest kamailio 5.8.x for
proper compatibility (5.7.x has some limited support, therefore 5.8.x is
highly recommended). Be also sure you set tls_threads_mode=2 and
--atexit=no. See:

  - https://www.kamailio.org/docs/modules/devel/modules/tls.html#tls.notes

Cheers,
Daniel
