The DID feature allows an extension to have a dedicated direct number. The dedicated number allows
calls to be made directly to the extension, without the caller going through the attendant.
The DID number may have from 1 to 4 digits (typically 4).
Each DID Trunk Interface card (VB-44520) supports up to 8 DID trunks.
Hardware Requirements
The -48V power supply is required.
