OpenSSL config issue with latest release

[leorg99]

I updated from 15-5.05 to the latest release published to docker hub (15-5.0.7?) and I noticed that I could no longer register with any clients over SIP-TLS. The logs indicated a protocol error with openssl. After digging a bit, it appears there is an openssl config issue.

Opening /etc/ssl/openssl.cnf and navigating to the end, I found:

[system_default_sect]
MinProtocol = TLSv1.2
CipherString = DEFAULT@SECLEVEL=2

Changing this to:

[system_default_sect]
MinProtocol = TLSv1.2
CipherString = DEFAULT@SECLEVEL=1

and restarting the container fixed the issue.
