So if I want to secure the signaling and media of a SIP based call using Asterisk, is this possible? That is, does Asterisk support TLS or SSL? If not, are there ways to implement SSL or TLS using an opensource product?<br />
<br />
Thanks,<br />

Asterisk support for TLS / SSL

IP telephony (Internet Protocol telephony) is a general term for the technologies that use the Internet Protocol's packet-switched connections to exchange voice, fax, and other forms of information that have traditionally been carried over the dedicated circuit-switched connections of the public switched telephone network (PSTN). Using the Internet, calls travel as packets of data on shared lines, avoiding the tolls of the PSTN. The challenge in IP telephony is to deliver the voice, fax, or video packets in a dependable flow to the user.
