Avaya IP Office Voice Streams Display

The Avaya Voice Streams Display provides a central point of administration, information and statistics for all calls that take place through the monitored PBX. It provides an easy interface to view call and line activity and to drill-down to see more detailed information.

Accessing the Display

From the Web Application go to the second (Instance) navigation pane, expand the required Avaya IP Office PBX name and then click on the Voice Quality item.

Display Data

This Display provides detailed Voice Stream data including the type, duration, MOS, Latency, Packet Loss% and Jitter for each. A graph is also included that shows the number of MOS Erlangs per interval categorized by their quality of service levels.

Drilling-down on an extension number in the Local or Remote columns will open the Avaya Phone Details Display which provides detailed information about the particular hardware device.

Drilling-down on the indicator in the View column will open the Avaya Voice Stream Details Display which shows a range of information about the particular call. The View column indicator will show as 'Details+Hops' if there are hops involved in the call or only 'Details' if there are no hops involved.

Latency

This will show call leg latency data. In VoIP terminology, latency refers to a delay in packet delivery. VoIP latency is a service issue that is usually based on physical distance, hops, or voice to data conversion.

Packet Loss

This will show call leg packet loss data. Packet loss occurs when one or more packets of data traveling across the VoIP network fail to reach their destination. Packet loss can be caused by a number of factors, including signal degradation over the network, oversaturated network links, corrupted packets rejected in-transit or faulty networking hardware.

Jitter

This will show call leg jitter data. In VoIP terminology, jitter is the variation in the time between packets arriving, caused by network congestion, timing drift, or route changes.
