VoIP Quality of Service Logging

Definition

The Voice-over-IP Quality of Service (QoS) monitoring feature collects data concerning end-to-end delay, jitter, and packet loss for RTP media traffic. For most IP end points (H.323 terminals and trunk lines, Attendant OMDs, and Media Gateways), the collection is done per call. The collected data is stored in a comma separated text file using the Call Information Logging output feature. The QoS feature can be switched on or off using I/O commands. Limitations: SIP end points, H.323 soft clients, and some older H.323 terminals cannot provide QoS data.

Settings

QoS is set by the administrator.
