Appendix B Voice Quality Manager
Introduction
The Voice Quality Manager (VQM) is a software package that resides on the MC55. 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.
