Secure calls

Depending on how your system administrator configures your phone system, your phone may support making and receiving secure calls.

Your phone can support these types of calls:

Authenticated call

The identities of the phones that are participating in the call have been verified.

Encrypted call

The phone receives and transmits encrypted audio (your conversation) within the Cisco Unified

Communications Manager network. Encrypted calls are authenticated.

Protected call

The phone is a secure (encrypted and trusted) device on the Cisco Unified Communications Manager server and is configured as a Protected Device in Cisco Unified Communications Manager Administration.

If Play Secure Indication Tone is enabled (True) in Cisco Unified Communications Manager Administration, the protected phone plays a secure or nonsecure indication tone at the beginning of the call:

•When end-to-end secure media is established through Secure Real-Time Transfer Protocol (SRTP) and the call status is secure, the phone plays the secure indication tone (three long beeps with brief pauses).

•When end-to-end nonsecure media is established through Real-Time Protocol (RTP) and the call status is nonsecure, the phone plays the nonsecure indication tone (six short beeps with brief pauses).

If the Play Secure Indication Tone option is disabled (False), no tone plays.

Nonprotected call

The phone does not have a Protected Device status in Cisco Unified Communications Manager. No secure or nonsecure indication tone plays.
