/mcpa logged-out user that there is an incoming call to a hunt list to which the line is a member, but the call will not ring at the phone of that line group member because of the logged-out status. To configure the Hunt Group Logoff Notification service parameter, perform the following steps. Procedure Step 1 From Cisco Unified CM Administration, choose System > Service Parameters. Step 2 From the Server drop-down list, choose the server that is running the Cisco CallManager service. Step 3 From the Service drop-down list, choose Cisco CallManager. The Service Parameter Configuration window appears. Step 4 In the Clusterwide Parameters (Device - Phone) section, configure values for the following Hunt Group Logoff Notification service parameter: Enter a name for the ringtone file that Cisco IP Phones play when a member of a line group (hunt group) has logged out. The default value for this service parameter is None, which indicates no ringtone. You can enter a maximum of 255 characters. Step 5 Click Save. The window refreshes, and Cisco Unified Communications Manager updates the service parameter with your changes. Hunt Group Interactions Interaction Feature If a phone is logged out of a line group and an extension on the phone is not shared, the line group does not ring that directory number (DN) in the line group. When the line group would normally offer the call to the DN, call processing skips the DN and acts as if the DN does not belong to the line group. Non-shared-line Directory Number Because the Log Out of Hunt Group feature is device-based, when a user logs a phone out, the feature affects only the logged-out phone. Calls to a line group that contains a shared-line directory number behave as follows: • The DN does not ring if all phones that share that DN are logged out. • The DN does ring if one or more phones that share the DN are logged in. • The audible ring on a phone that is logged out is turned off by default. Cisco Unified Communications Manager provides a system parameter that can be set, so that a different ring tone plays when a call comes in to a logged-out hunt group member.
