RTP Statistics
The RTP Statistics page provides detailed information about the
established call is provided. When Quadro serves as an RTP proxy,
this page displays two groups (legs) of RTP statistics. For example,
when calling from an IP Phone attached to the Quadro’s IP line to an
external SIP destination or from one external SIP destination to
another through the Quadro’s Auto Attendant. Each group of
parameters describes characteristics of a piece of RTP stream
composing an overall SIP session. Normally, one leg describes the
RTP stream from caller to the Quadro and the other leg describes the
RTP stream from Quadro to the destination.
Quality - estimated call quality, which depends on RTP statistic.
Below is the legend for Call Quality definitions on the displayed RTP
Statistics:
excellent – RX Lost Packets < 1% & RX Jitter < 20
good - RX Lost Packets < 5% & RX Jitter < 80
satisfactory - RX Lost Packets < 10% & RX Jitter < 150
bad - RX Lost Packets < 20% & RX Jitter < 200
very bad - RX Lost Packets > 20% or RX Jitter > 200
