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.
