A wide range of performance metrics are generated. Some are based on current values, such as jitter buffer nominal delay and round trip delay, while others cover the time period from the beginning of the call until the report is sent, such as network packet loss. Some metrics are computed using other metrics as input, such as listening Mean Opinion Score (MOS), conversational MOS, listening R-factor, and conversational R-factor.

Dynamic Noise Reduction

Dynamic noise reduction (DNR) provides maximum microphone sensitivity, while automatically reducing background noise— from fans, projectors, heating and air conditioning—for clearer sound and more efficient conferencing.

There are no related configuration changes.

Treble/Bass Controls

The treble and bass controls equalize the tone of the high and low frequency sound from the speakers.

The SoundStation IP 7000 phone’s treble and bass controls can be modified by the user (through Menu > Settings > Basic > Audio > Treble EQ or Bass EQ).

Configuration changes can performed centrally at the boot server:
