AES Encryption DescriptionAES Encryption Description
• Previous versions of Encryption were only available between Zultys phones.
• Version 3.0 adds encryption between the phone and the MX. This ensures that calls to the PSTN are encrypted to the edge of the IP network.
• Encrypted calls can be terminated on an AA or even the VM server.

Call ScenariosCall Scenarios
• When calling the PSTN – The call can be encrypted between the phone and the MX
• When calling another ZIP phone and the call goes to Voicemail – This call can be encrypted. The saved voicemail will be recorded unencrypted.
• When calling the PSTN and recording the call – This is a feature that is currently not enabled.
• When calling through an ITSP – These calls cannot be encrypted as the MX will not terminate the RTP stream (Unless the ITSP uses an MX!).
• When a call goes over ALG to an ITSP that is being recorded – This call cannot be encrypted – see above.
