Adding or Editing DID Information

When you add or edit DID information, you specify a prefix and the range of phone numbers to use for direct inward dialing.

Your PBX administrator may provide you with discontinuous ranges of DID extensions or even groups of DID extensions with different prefixes. Enter each range separately until they all appear in the list on the DID Info page of the Telephony screen.

For example, your PBX administrator may supply 100 DID extensions with the following ranges:

You can enter each range separately in the Add DID Range Entry dialog box to make them all available to Vocera.

Tip: The DID numbers that you specify must be full 10-digit telephone numbers with area code in the US locale (or full numbers with city and region codes, in other locales).

To add or edit DID information in the Add DID Range dialog box, follow these steps:

  1. Navigate to the Telephony-DID Information section in the Add/Edit Facility page.
  2. Click Add DID to display the Add DID Range dialog box.
  3. Enter the area code and prefix assigned to the range in the Prefix field.

    For example, if the local area code of the PBX is 408, and the corporate prefix for all extensions is 790, you typically enter (408)-790. In some situations, your PBX administrator may assign a different prefix for you to use.

    To provide maximum flexibility, Vocera does not check the value you enter in this field. If necessary, you may enter country and city codes, as well as extensions whose length is shorter or longer than four digits. For example, if your deployment has five-digit extensions, you may want to enter a prefix such as (408)-79.

    Important: Enter the area code and full prefix that make a complete dialing string when combined with a value in the range of extensions. Vocera combines the extension and the value in the Prefix field to create a call-back number for paging.
  4. In the Match section, choose one of the following options to define the range of DID numbers:
    • Choose All Desk Extensions with Prefix to use the entire range of numbers represented by the value in the Prefix field.

      For example:
      • If the value in the Prefix field is (408)-790, you are assigning the range (408)-790-0000 through (408)-790-9999 as DID extensions. The extensions available for assignment to Vocera users and groups are 000 through 999, 0000 through 9999, or 00000 through 99999.
      • If the value in the Prefix field is 5, you are assigning any number that starts with a "5". The extensions available for assignment to Vocera users and groups are 500 through 599, 5000 through 5999, or 50000 through 59999.
    • Choose Desk Extensions Starting With and specify a starting value to use a subset of the range of numbers represented by the value in the Prefix field.

      For example:
      • If the value in the Prefix field is (408)-790, and you enter 8 in the Desk Extensions Starting With field, you are assigning the range (408)-790-8000 through (408)-790-8999 as DID extensions. The extensions available for assignment to Vocera users and groups are 8000 through 8999.
      • If the value in the Prefix field is (408)-790, and you enter 94 in the Desk Extensions Starting With field, you are assigning the range (408)-790-9400 through (408)-790-9499 as DID extensions. The extensions available for assignment to Vocera users and groups are 9400 through 9499.
      • If your PBX passes 59xx to Vocera, enter 5 in the Prefix field and 9 in the Desk Extensions Starting With field. This means you are assigning the range 5900 through 5999 as DID extensions. The extensions available for assignment to Vocera users and groups are 900 through 999.
    • Choose Desk Extensions in Range and enter beginning and ending values value to specify a range of phone numbers within the set represented by the value in the Prefix field. This is the most typical situation.

      For example:
      • If the value in the Prefix field is (408)-790, and you enter 8000 To 8999 in the Desk Extensions In Range field, you are assigning the range (408)-790-8000 through (408)-790-8999 as DID extensions. The extensions available for assignment to Vocera users and groups are 8000 through 8999.
      • If the value in the Prefix field is 5, and you enter 501 To 549 in the Desk Extensions In Range field, you are assigning the range 5501 through 5549 as DID extensions. The extensions available for assignment to Vocera users and groups are 501 through 549.
