Tips
• Your phone may play an audible indicator to alert you when a call is ringing on the monitored line
(BLF Pickup only).
• BLF Pickup answers the oldest ringing call first (if the line that you are monitoring has more than
one ringing call).
Making and Receiving Secure Calls
Depending on how your system administrator configured 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 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.
• Protected call—The phone is a secure (encrypted and trusted) device on the Unified CM server and
is configured as a “Protected Device” in Unified CM Administration.
If “Play Secure Indication Tone” is enabled (True) in Unified CM 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 the 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).

Otherwise, the call rings on your phone for you to answer.
If you press the BLF Pickup button when the monitored line is not ringing,
your phone will speed dial the line number.
