User’s Guide

Also, the jitter calculation for Surveyor only measures network jitter. The application itself may implement a jitter buffer, which could make for further differences between the reported RTCP jitter and the jitter measured by Surveyor.

The difference between the RTCP jitter and Surveyor-calculated jitter may provide some clues as to what is happening with calls where high jitter rates are disrupting network QoS.

Configuring Multi-QoS

Logic internal to Surveyor decodes the VoIP frames and organizes call information into easy-to-read graphs and tables. Configuration is not required to use the Multi- QoS logic; however, the displays can be customized to view exactly the call information you want to see.

Multi-QoS is primarily configured from the Configuration tab. However, there is some configuration for Multi-QoS that is done on a per-module basis. Module configuration sets up the monitoring of Multi-QoS only, effectively increasing Multi-QoS monitor performance. See the following subsection on performance optimization for a description.

The Multi-QoS Configuration tab in Monitor mode shown below. Different options will be enabled/disabled in Monitor mode.
