You can watch the video above for an overview and click over to Cellcrypt's detailed explanation page for a full run down of how it works (uses an encrypted mobile protocol which runs over IP). Using CellCrypt adds a few seconds to the calling process, but if you're in an industry where secrecy is of the utmost concern, then this is definitely a solution to look into.
