Kamailio suddenly stops - sr-users

28 Dec 2020


      Hi there!
When I start my webrtc kamailio suddenly stops.
I can see this on syslog:

      .
      Contiene el binario de propósito general para la línea de órdenes
      /usr/bin/openssl,
      útil para operaciones criptográficas como:
       * creación de parámetros clave RSA, DH y DSA;
       * creación de certificados X.509, CSR y CRL;
       * calcular resúmenes de mensajes;
       * cifrado y descifrado con cifras;
       * probar clientes y servidores SSL/TLS;
       * gestión de correo firmado o cifrado S/MIME.
Should I use another version of openssl, or maybe use gnutls?
