    Please Note: The Data Call (CSD Line) must be enabled on your SIM card and the phone must be used on a GSM network (UMTS, 3G, CDMA network standards are not currently supported by our Secure Voice GSM). These services may not be available via all operators, and may require separate subscription. It is the customer's responsibility to ensure that CSD services are available with their preferred GSM operator.
    It is not a voice call, that is how.

    Yep, data calls, VoIP calls etc. where the call-data can be manipulated of course would allow crypting, and indeed voice call are not having this option.
