This section provides information about how the Listed Directory Number (LDN) feature interacts with other features on the system. Use this information to ensure that you receive the maximum benefits of Listed Directory Number in any feature configuration.

Night Service

If you activate the Night Service capability, and a night console is not assigned or is not operational, the system routes:
  • Incoming Direct Inward Dialing (DID) LDN calls route to a designated DID LDN night extension. If no DID LDN night extension is designated, the system routes DID LDN calls to the attendant
  • Incoming central office (CO) or foreign exchange (FX) trunk calls to the night destination that is specified for the trunk group. If no night destination is specified for the trunk group, the system routes the calls to the normal incoming destination for that trunk group.
  • Internal calls and coverage calls to the attendant to the DID LDN night extension during night service.

Call Coverage and Tenant Partitioning

If a covered call does not route to an attendant in the first tenant group, you can route it to an attendant group of a different tenant partition. For example, you can reroute a call to Tenant Group B if the call is to cover to an attendant for Tenant Partition A  but does not route to the attendant or is received out of hours when Attendant Group A is unstaffed.
To reroute the covered calls to another tenant attendant group, Tenant Attendant group B in this example,
  1. In the vector for the tenant A attendant vectoring VDN, add a failure branch to a route-to ldn_number with cov y if unconditionally step for the LDN extension for the tenant group B TN number.
  2. Set the with coverage parameter of the route-to step must be set to cov y because the calls are covered. Else, the calls don’t route to the VDN. Also, set the Cvg Enabled for VDN Route-to party? field of original coverage path, which covers to Tenant A Attendant vectoring VDN, to y.
