If you select Call Progress tone supervision, the VoxBox detects a busy tone based
on the cadence parameters set using code *371. It detects an answer when voice is
recognized. The VoxBox does not check for Ring-Back tone cadences.
The VoxBox distinguishes between two types of transfers:
•
Transfer to operator
•
Transfer to the rest of the extensions
Table 3-9 explains how to program supervised, semi-supervised and
non-supervised transfers to the operator and to the rest of the extensions.
