DLR Misconfiguration Report

ℹ️ About Cards
1

The Dynamic Location Routing (DLR) Miconfiguration Report Identifies misconfigurations based on the numbers assigned to teams and the defined DLRs. Only active Direct Inward Dialing (DID) numbers require a DLR. A ZIRO DID that requires a DLR may incur costly fines for non-compliance with 911 calling regulations. Conversely, an orphan DLR entry—one that is not associated with any number in Teams—can lead to unnecessary 911 calling service fees.

When is a DLR considered orphaned?

A number is considered orphaned when All 3 conditions are met

  • The number is defined as a DLR entry
    AND
  • The number is not assigned to a UPN in Teams
    AND
  • The number is not assigned to a ZIRO Emergency Numbers Exception Group.

What are the 3 types of Misconfigurations

  • Missing DLR - A user or resource account with an assigned ZIRO DRaaS number requiring Emergency Calling missing a DLR
  • Missing Emergency Number DLR - An Emergency Callback Number (used as ELIN or Shared Calling Number) missing a DLR
  • Orphaned DLR - A DLR that is not required

:warning: Important Known Limitations

This report does not identify missing DLRs on DIDs used as a “Shared Main Line” by users with extensions. These DIDs are typically tied to Auto-Attendants and Call Queues configured outside of ZPM. The DLR entries for these “Shared Main Line” DIDs must be created manually.
