Single Site Customer

Since this is a single site customer, it does not require a Site Code.

  Dialing Format (A-Party) Display Format (B-Party) Notes
Intra-Site Dialing
  • Extension (subset of DID number) (for example, 4321 or 54321 if extension prefix is used)
  • Site Code + Extension for (example, 81134321
  • Extension

Even though a site code has been assigned, users are not aware of it.

Note:

Explicit extension prefix may not be required and it can be included as the first digit of the extension.

DN Format Extension (for example, 4321)   All extensions must be unique. If there are overlapping extensions, then the DN format of the extension only is not supported. Site Codes are required in this case. IPPBX configuration is done at the customer level.
Voice Mail Voice Mail Pilot number is also an extension (for example, 4000 or 54000 if using an extension prefix) The Voice Mail setup cannot be a child of another location; it must have its own site code. If the extensions for the VM are reserved in the location, then the Dial Plan can be used to prefix the VM extension with the SLC so the user only dials the extension
