Hello, I am trying to build kamailio from source. I am a newbie to kamailio. In the download area of 1.5.2, http://www.kamailio.org/pub/kamailio/1.5.2/src/, there are two files: kamailio-1.5.2-notls_src.tar.gz 3.3M kamailio-1.5.2-tls_src.tar.gz 3.4M I have a question: what is the difference, in short, between these two tar balls ? Regards, Mark
