Chapter 1 Introducing the Prestige 25
Comfort Noise Generation
The Prestige generates background noise to fill moments of silence when the other device in a
call stops transmitting because the other party is not speaking (as total silence could easily be
mistaken for a lost connection).
Echo Cancellation
The Prestige supports G.168, an ITU-T standard for eliminating the echo caused by the sound
of your voice reverberating in the telephone receiver while you talk.
QoS (Quality of Service)
Quality of Service (QoS) mechanisms help to provide better service on a per-flow basis. The
Prestige supports Type of Service (ToS) tagging and Differentiated Services (DiffServ)
tagging. This allows the Prestige to tag voice frames so they can be prioritized over the
network.
Fax Tone Detection and Pass-through
The Prestige automatically detects fax messages and sends them over PCM G.711.
Auto-provisioning
Your voice service provider can automatically update your Prestige’s configuration via an
auto-provisioning server.
Auto Firmware Upgrade
The Prestige gives you the option to upgrade to a newer firmware version if it finds one during
auto-provisioning. Your voice service provider must have an auto-provisioning server and a
server set up with firmware in order for this feature to work.
Manual Firmware Upgrades
Use the web configurator to upload updated firmware to your Prestige.
Ease of Installation
Your Prestige is designed for quick, intuitive and easy installation. Physically, its compact size
and lightness make it easy to position anywhere in your busy office.
