Ranges and Phone Number Blocks

The Ranges screen allows you to see Ranges you have created or add new Ranges.

A Range is a logical grouping of Direct Inward Dialing(DID)/Direct Dial-In(DDI) numbers. The Range is usually named after the location the number block is located in but a number block could be split across two ranges or a Range could cover multiple physical locations. You would normally decide to split Ranges or Number Blocks when you are using the PowerShell Commands to get available numbers from a Range. The PowerShell commands allow you to find available numbers in a Range and therefore a Range should be defined to easily support the bsuiness processes involved in allocating numbers.

The Ranges screen allows you to easily see what percentage of numbers are used in the Numbers Usage column. This visual representation allows an administrator to see that new numbers may need to be allocated to a range to support new users.
