TLS 1.2 support in kannel

Hello,

I have similar issue with SSL and kannel, in SMSBOX it appears the following
errors :

2018-10-01 21:11:12 [3345] [8] ERROR: Couldn't fetch
<https://www.joe.com/input.php?from=%2B712341234>
2018-10-01 21:11:32 [3345] [8] ERROR: SSL write failed: OpenSSL error 1:
error:00000001:lib(0):func(0):reason(1)
2018-10-01 21:11:32 [3345] [8] ERROR: SSL write failed: OpenSSL error 1:

2018-10-01 21:11:32 [3345] [8] ERROR: SSL read failed: OpenSSL error 1:
error:00000001:lib(0):func(0):reason(1)

It is related to the fact the web site drop TLS1 and TLS1.1 and is using
only TLS 1.2 and up. Does someone got similar issue and how to resolve or
patch it ?

Thanks in advance for your help
