What is Call Vectoring?
Issue 4 September 1995
1-3
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:
1. Voice Response Unit
2. Dialed Number Identification Service
3. Vector Directory Number
Figure 1-2. Call Vectoring
As Figure 1-2 illustrates, 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.
