Introducing Cisco Call Back
SDI Trace and Alarm
The Cisco Extended Functions service uses the SDI Trace and Alarm libraries.
The libraries generate trace and alarms to the Event Viewer. The alarm library
publishes information to the Cisco RIS Data Collector service about the CEF
service. For more information about trace and alarms, refer to the
Cisco CallManager Serviceability Administration Guide.
Cisco Extended Functions Service Dependency
Cisco Call Back uses the Cisco Extended Functions service, which depends on the
following services (see
Figure 4-2 ):
• Cisco CallManager—Ensure a minimum of one Cisco CallManager service
is running in the cluster, but the service need not be on the same server as
CEF.
• Cisco CTIManager—Ensure a minimum of one Cisco CTIManager service is
running in the cluster, but the service need not be on the same server as CEF.
• Cisco Database Layer Monitor—Ensure one Cisco Database Layer Monitor
service is running on the same server as CEF.
• Cisco RIS Data Collector—Ensure one Cisco RIS Data Collector service is
running on the same server as CEF.
Tip Install all the services on one server for one-server Cisco CallManager systems.
