Figure 10. Phantom Calling Groups
Phantom Extensions
If more than 30 extensions require coverage to the operator, phantom
extensions can be used after all of the phantom calling groups are used up.
This setup is slightly different than the previous two scenarios. In this case, the
published DID number is the number for the phantom extension. The actual
telephone has Shared SA buttons of the phantom extension, so the call rings at
the telephone with the Shared SA button. The phantom extension covers to the
operator, and the operator has the ability to send the calls to the original
extension's voice mail using the Direct Voice Mail feature.
To set up phantom coverage to the operator before going to voice mail, do the
following:
Assign extension (for example, 114) to a coverage group. Assign a
Group Cover button to the operator if a DLC, or assign the coverage
group to ring at the QCC.
Assign a phantom extension to a number (for example, 214. You may
have to renumber 214 first.) It's best to use the MFM number for that
extension (100 higher than the extension number) to prevent confusion.
