USING QOS MONITORING
This chapter describes how to use the QoS Monitoring feature to gather
and view statistics on 3Com IP phones.
QoS Monitoring is implemented across three components in a VCX
system:
VCX Call Processor
3Com IP Phones
XML Accounting Server
Overview The QoS Monitoring feature covers 3Com IP phones as endpoints (310x).
With QoS Monitoring you can:
Obtain measurements of layer-2 configuration changes
Identify faulty phones or routes
Recognize periods or network episodes with sub-standard voice
quality
View generated statistics using SNMP
Additionally, you can configure:
One or more monitored phones/subnets
Thresholds for QoS statistics generation by the phones on those
monitored subnets
Alarm thresholds for notifications to be issued based on QoS
parameters
Third party phones, soft phones, and convergence clients are not
supported.
