Appendix B Voice Quality Manager

Introduction

The Voice Quality Manager (VQM) is a software package that resides on the MC95XX. VQM enables a set of
features for Voice over WiFi (VoWiFi) calls, and a sub-set of those features for cellular line calls. The VQM user
interface is designed to be intuitive and easy to use, so complex tasks such as enabling the Acoustic Echo
Canceller (AEC) while a call is in progress are done with very little or no user intervention.

Features

The VQM software:
• Improves the voice transmission quality without using additional battery power.
• Turns on the AEC for VoWiFi calls automatically, without user intervention.
• Prioritizes the outgoing audio IP packets.
• Provides user-selectable audio modes (speakerphone and handset) with a single tap of the VQM icon. A
VQM icon in the title bar of the device indicates the audio mode currently in use.
NDIS 5.1 compliant.
