What is Call Vectoring?

Working together, these components direct incoming and ASAI event reports and requests to the desired answering destinations, and they specify how each call is to be processed. Call Vectoring may be illustrated as follows:

TRUNK GROUP 1

TRUNK GROUP 2

VRU1 TRANSFER

VDN3 1

VDN 2

VECTOR 1

VDN 3

DNIS2 DIGITS

VDN 4

INTERNAL CALL VDN 5

1.Voice Response Unit

2.Dialed Number Identification Service

3.Vector Directory Number

VECTOR 2

Figure 1-2. Call Vectoring

As Figure 1-2illustrates, an incoming call to the DEFINITY G3 switch with Call Vectoring enabled is first directed to a Vector Directory Number (VDN). A VDN is an internal telephone number that, in turn, directs the call to a specific call vector. The VDN represents the call type or category (for example, billing, customer service, etc.), and thus, it defines the service desired by the caller. Multiple VDNs may point to the same or to different vectors, depending upon whether the relevant calls are to receive the same or different treatment.

The vector, which is the heart of Call Vectoring, is a set of commands that define the processing of a call. The type of processing that a call receives depends upon the commands included within the vector. For example, a call can be queued and then routed to another destination.
