[SR-Users] Enable session_id in ServerHello for TLS

[Daniel-Constantin Mierla]

Hello,

thanks for reporting back it's working -- please keep the mailing list 
cc-ed, so people looking for same issue will be able to find it when 
searching the web archive.

I am using snom3xx with tls and kamailio 3.x a lot, never had issues, 
but I have no clue about the softphone.exe

Cheers,
Daniel
