Avaya Voice Priority Processor Overview

The Avaya Voice Priority Processor is an Ethernet LAN device that works with access
points (APs) to provide QoS on the wireless LAN. Voice packets to and from the Avaya
Wireless IP Telephones are intercepted by the Avaya Voice Priority Processor and
encapsulated for prioritization as they are routed to and from an IP telephony server.
1.1

Avaya Voice Priority Processor (AVPP), QoS and Security

The Avaya Voice Priority Processor (AVPP) is an Ethernet LAN device that works with the
AP to provide quality of service QoS on the wireless LAN. Voice packets to and from the
Avaya 3641/3645 Wireless IP Telephones are intercepted by the Avaya Voice Priority
Processor and encapsulated for prioritization as they are routed to and from an IP
telephony server or gateway. This mechanism is fully compatible with the IEEE
802.11a/b/g standards.

The latest software versions are required to support the features described in
this document.
1.2

Avaya Voice Priority Processor Models

The AVPP is available in three models. Which model is selected for your facility depends
on current and expected capacity. All AVPPs within a subnet must be the same model
type.
•
AVPP 100 – Serves 80 calls simultaneously.
•
AVPP 20 – Serves 20 powered-on handsets.
•
AVPP 10 – Serves 10 powered-on handsets.
See the following capacity tables for multiple AVPP system capacities.
All AVPP models are installed, configured and administered according to the instructions
in this document. The model information is available on the Software Version screen. See
section 7.3 Software Version.
1.3

The Timing Function

Avaya Voice Priority Processors provide the connection or "gateway" to the IP PBX for the
Wireless IP Telephones and the "timing" function for active calls. This "gateway" function
is distributed across the AVPPs.
The number of active AVPPs is determined dynamically. Whenever AVPPs are added to or
removed from the system, the distribution of the "timing" function for active calls is
affected.

Multiple Avaya Voice Priority Processors

Multiple AVPP environments are those which have more than one Avaya Voice Priority
Processor. Up to four AVPP 10 models or up to two AVPP 20 models may be installed in
