[SR-Users] Unable to enable TLS on Kamailio

[Tomi Hakkarainen]

Hello,

I finally got Kamailio to start with TLS.
I tried with multiple openssl versions last with 
openssl version
OpenSSL 1.1.0g  2 Nov 2017

also updated Kamailio to 5.0.4 from Suse repo's
and had no luck with those two.

I decided to compile Kamailio 5.1 and with little fling with database I think I overcame the TLS starting trouble… 
Now it cranshes as it cannot connect to Asterisk DB -> will jack with that tomorrow.

Thank you for your guidance as with it I focused on the openssl and finally have I hope working setup...

Regards,
 Tomi
