■ Serving as a coverage point for specific call operations (for example,
sending calls to a secretary during the day and to AUDIX at night).
VDN as a coverage point is illustrated in Chapter 4, "Basic Call Vectoring".
Service Observing VDNs
The Service Observing feature provides the option of being able to observe
VDNs with G3V3 and later releases. With this option an observer selects a
specific VDN and bridges onto calls (one call at a time) that have just started
vector processing for that VDN. The observer hears all tones, announcements,
music, and speech that the caller and the agent hear and say, including Call
Prompting and caller dialing. Also, the observer hears VDN of Origin
announcements. Once the system makes an observing connection to a call in
vector processing, it maintains the connection throughout the life of the call until
the call is disconnected or until the observer hangs up. This is true even if the call
is routed or transferred externally. See “Service Observing” in the

Vector Control Flow
Vector Processing starts at the first step in the vector and then proceeds
sequentially through the vector unless a
goto
command is encountered. Any
steps left blank are skipped, and the process automatically stops after the last
step in the vector.
The Call Vectoring ‘‘programming language’’ provides three types of ‘‘control
flow’’ that serve to pass vector-processing control from one vector step to
another. Control flow types are described in the following list.
■ Sequential flow passes vector-processing control from the current vector
step to the following step. Most vector commands allow for a sequential
flow through the vector.
NOTE:
Any vector command that fails automatically passes control to the
following step. The success and/or failure criteria for the Call
Vectoring commands is discussed in Appendix A.
■ Unconditional branching
unconditionally
passes control from the current
vector step to either a preceding and/or succeeding vector step or to
another vector (for example,
goto step 6 if unconditionally
).
■ Conditional branching
conditionally
passes control from the current
vector step to either a preceding and/or succeeding vector step or to a
different vector. This type of branching is based on the testing of
threshold conditions (for example,
goto vector 29 if staffed-agents in split
6 < 1
).
