Making and Receiving Secure Calls

Depending on how your system administrator has configured your phone system, your phone might
support making and receiving secure calls.
Your phone can support these types of calls:
• Authenticated call—The identities of the phones participating in the call have been verified.
• Encrypted call—The phone is receiving and transmitting encrypted audio (your conversation)
within the Unified CM network. Encrypted calls are authenticated.
