Vector Directory Number This screen defines vector directory numbers (VDN) for the Call Vectoring
feature. A VDN is an extension number used to access a call vector. Each VDN is
mapped to one call vector.
VDNs are software extension numbers (that is, not assigned to physical
equipment). A VDN is accessed via direct dial CO trunks mapped to the VDN
(incoming destination or night service extension), DID trunks, and LDN calls. The
VDN may be Night Destination for LDN.

Guestworks Call Vectoring Guide for more information.
