The Unified Communications applications' features and services are administered using the native application portals and accessed from the Dedicated Instance configuration tab in Control Hub.

The Partner or Customer administrator can view the UC application's networking and datacenter information by clicking on CallingDedicated InstanceManageUC application, which opens a right pane in Control Hub.

The following details are displayed on the right pane:

  • Version - Current version of the UC application

  • Server - Fully qualified domain name of the UC application

  • IP address - Internal IP address of the UC application

  • Server Role - Indicates whether the node is a Publisher/Primary or Subscriber/Secondary

  • Services - Provides a list of only those services that are activated on the node.

    List of services available are:

    • Provisioning (only for Publisher)

    • Call Processing

    • CTI Manager

    • Music on Hold (MOH)

    • Trivial File Transfer Protocol (TFTP)


    The sync is scheduled every 24 hours, for the changes made in application to reflect in Control Hub.
  • Datacenter - Datacenter where the node is deployed

  • Voice Service Domain - Voice service domain for Internal and MRA registrations

  • Public IP address — Internet facing IP address (applicable only for the Expressway Edge nodes)

Key Performance Indices (KPIs)

Field Title

Description

Poor Calls

Count of the total poor calls and the percentage from the total calls in the past 1 hour. A call for which the SCSR value exceeds the long call and short call SCSR threshold is graded as a poor call. For more information, see Unified CM Call Quality Grades .

If you see an unusually high value of poor calls, it indicates that there could be network issues related to bandwidth, QoS settings, and so on.

Failed Calls

Count of the total failed calls and the percentage from the total calls in the past 1 hour. If the origination and termination cause code of a CDR are not one of these values—'0', '1', '2', '3', '16', '17','31','126','127','393216','458752','262144', then a call is graded as a failed call.

If you see an unusually high value of failed calls, check the call failure report.
