{wiki=Vector_directory_number}
A Vector Directory Number (VDN) is a term used in the context of telephony, especially in relation to call centers and Automatic Call Distribution (ACD) systems. A VDN serves as a unique identifier for a specific set of routing instructions within a call routing system. When a call is directed to a VDN, the call routing system retrieves and executes the corresponding routing instructions to determine how the call should be handled.
