This will enable you to encrypt the information about what numbers are being called etc... https://wiki.asterisk.org/wiki/display/AST/SIP+TLS+Transport The other is SRTP so that the actual audio is encrypted :- http://www.voip-info.org/wiki/view/Asterisk+SRTP SRTP is supported natively in Asterisk 1.8 and later so you should definetly upgrade.
