Tips

Your phone might 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 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.

Protected call—The phone is receiving and transmitting encrypted audio (your conversation) with another phone. A protected call provides a similar level of security as an encrypted call, but adds additional security. If the call is protected at both ends, a security tone plays at the beginning of the conversation. Some features, such as conference calling, shared lines, Extension Mobility, and join across lines are not available when protected calling is configured. Protected calls are not 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.
