While a call is in progress, view RTP/RTCP QoS metrics, such as
packet loss and jitter.
•

Fundamentals NN43001-368.

SNMP interface

Simple Network Management Protocol (SNMP) interfaces with the
traffic-reporting system so that any third-party system, can have a simple,
standards-based interface into the system traffic reports.
For details about the SNMP interface, see Communication Server 1000
Fault Management – SNMP NN43001-719.

Heterogeneous environments

In a heterogeneous environment, with a mixture of Nortel equipment and
third-party equipment, voice-quality monitoring, detection, and alarming
are performed only on IP endpoints that have voice-quality monitoring
capabilities.
For information about IP endpoints and their voice-quality capabilities in
the system, see
180).
