Specify essential DID Range information

This step is mandatory.

Enter the following information.


Parameter

Description
Directory Unique user-friendly name identifying the DID Range. Specify a name of up to 16 characters.
Range size The number of directory numbers in the range.
First Directory number The first external directory number (full national telephone number including the leading zero) in the range. Either type in the number (noting that if the Number status of the parent PBX object is Normal, Ported from, or Non-geographic, the directory number must be within an active Number Range), or click on the ellipsis symbol at the end of the field to select from the list of numbers not currently in use, as follows.
  • Select a Number Range.
  • Select a boundary (10, 50, 100, 500, or 1000) to determine how the starting number in the range should be allocated, or select None if any starting number is acceptable.
  • Select Manual or Automatic block selection.
If you select Automatic, the NE allocates a block of numbers that meets your requirements for range size and starting boundary. It also shows the continuous range of unallocated numbers around the selected block, to help you determine how the available numbers in the range will be fragmented by your selection. If necessary, you can go back and specify a different range size, number range and/or boundary. If you select Manual, the NE displays a list of all possible number blocks meeting your requirements that could be allocated, again showing the range of unallocated numbers around each number block. Select an appropriate block from the list, or go back and specify a different range size, number range and/or boundary if necessary.
First code The code that will be pulsed to the PBX to identify the terminal corresponding to the first directory number in the range. Specify a numeric code of 2-10 digits (if the Call Agent signaling type of the parent PBX is Analog line / T1 CAS), or 2-25 digits (if it is SIP).
Limit incoming calls Specifies whether to limit the number of simultaneous incoming calls to this range of numbers. Values:
  • True
    The number of simultaneous calls cannot exceed the value specified in the Maximum incoming calls field.
  • False
    The number of simultaneous calls is not limited.
Maximum incoming calls This field appears only if Limit incoming calls is True. The maximum number of simultaneous incoming calls to this range of numbers. When the limit is reached, any further calls will be treated as though the PBX is busy.
