Logging Out of Hunt Groups
If your organization receives a large number of incoming calls, you might be a member of a hunt group. A hunt group includes
a series of directory numbers that share the incoming call load. When the first directory number in the hunt group is busy, the
system hunts for the next available directory number in the group and directs the call to that phone. When you are away from
your phone, you can prevent hunt group calls from ringing your phone by logging out of hunt groups.
Log out of hunt groups to temporarily block hunt group calls
Choose Options > HLog. Your phone screen displays, “Logged out of Hunt Group.”
Log in to receive hunt group calls
Choose Options > HLog.
Tip
Logging out of hunt groups does not prevent non-hunt group calls from ringing your phone.
Remote-in-Use
The “In Use Remote” message and icon display on a Cisco Unified Wireless IP Phone 7921G when another phone that
shares your line has a connected call and Privacy is disabled. You can place and receive calls as usual on the shared line, even
when the “In Use Remote” message or
icon displays.
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-secure call—At least one of the participating phones or the connection does not support these security features, or the
phones cannot be verified.
Check the security level of a call
Look for a security icon in the top right corner of the call activity area, next to the call duration timer:
Authenticated call
Encrypted call
Neither security icon appears if the call is non-secure.
Determine if secure calls can be made in your company
Contact your system administrator.
Note There are interactions, restrictions, and limitations that affect how security features work on your phone. For more
information, ask your system administrator.
