command to configure the advantage factor. When the system calculates the ICPIF value, this
advantage factor is subtracted to modify ICPIF and MOS values and thus both the objective and
subjective factors are considered when you evaluate the voice quality.
Configuration prerequisites
A voice test requires cooperation between the NQA server and the NQA client. Before a voice test,
make sure that the UDP listening function is configured on the NQA server. For the configuration of
UDP listening function, see Configuring the NQA Server .
