RTP Statistics
The
RTP Statistics
page provides detailed information about the
established call is provided. When QX1000 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 QX1000’s IP line to an
external SIP destination or from one external SIP destination to
another through the QX1000’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 QX1000 and the other leg describes
the RTP stream from QX1000 to the destination.
Quality
- estimated call quality, which depends on RTP statistic.
Below is the legend for Call Quality definitions on the displayed RTP
