Explanation

Cisco Expressway zone media encryption settings offer specific operational modes-not cipher algorithms. The configurable options are: Auto, Force encrypted, Force unencrypted, and Best effort. 'Force unencrypted' is a valid zone-level setting that instructs the Expressway to strip encryption from media on that zone. AES and 3DES are cryptographic algorithms (not zone modes), and IPsec is a network-layer security protocol-none of these are selectable as a zone encryption mode in the Expressway UI.
