What is a Location?

UC Monitor administrators create Locations that correspond to network entities such as branch offices, departments, or buildings. Location definitions determine how data is displayed in reports. UC Monitor reports organize call performance data based on Location or Sending Location. These categories are further identified as <Unassigned>, <None>, or <External>, as explained in the following list:

Receiving Location

Call data that is categorized as Location was received by the indicated Location.

Sending Location

Call Data that is categorized as Sending Location was sent from the indicated Location.

<Unassigned>

The <Unassigned> Location identifies IP phones that were observed during monitoring but whose IP addresses are not part of the subnets in your Locations. An <Unassigned> Location is not the same as a Location of <None>.

A Location is <Unassigned> for reasons such as:

• Locations have not been defined for the IP address ranges of some phones in the network.
• A device pool is misconfigured in a Cisco Unified Communications Manager.
• The phone is misconfigured, placed in an unexpected VLAN or with an unexpected IP address.

Call traffic from endpoints in new subnets is labeled as <Unassigned> until the administrator creates a Location definition for those subnets. Periodically, the administrator exports a list of current Location definitions and verifies that it reflects recent changes to the network and telephone system.

<None>

A Receiving Location or Sending Location of <None> indicates that the IP address of the endpoint was not determined, for reasons such as the following:

• Call setup failed before the number was determined.
• A directory number in the system is not assigned to an endpoint.
• The origination party abandoned the call before it was answered.

  Note: Abandoned call legs that have metrics are displayed in the Call Leg Details report. In addition, you can see these calls in the Calls Overview when the option to “Show abandoned calls” is enabled in the Settings dialog.

<External>

The <External> Location appears only when a Microsoft environment is monitored. This Location identifies endpoints that are reported to the front-end server as remote. UC Monitor uses this Location definition for endpoint addresses outside your firewall, or behind a NAT device, that make remote access connections through an edge server. Such endpoints are assigned a temporary IP address, usually a private address, that potentially overlaps with internal IP addresses in use by other endpoints.
