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 all phones participating in the call have been verified.

•Encrypted call—The phone is receiving and transmitting encrypted audio (your conversation) within the Cisco IP network. Encrypted calls are also authenticated.

•Non-securecall—At least one of the participating phones or the connection does not support these security features, or the phones cannot be verified.
