Reading the call screen values of delay, jitter and packet loss isn’t self explaining.
Call Screen Description
In the trace and in the log you can see the following:
G729AB,60(0,0) Codec, packet size (delay in ms, jitter in packets) it is shown two times for incoming and outgoing traffic.
In the PBX under call it looks like that:
G729AB (30,7,241) Codec (delay in ms, jitter in packets, packet loss in packets) it is shown two times for incoming and outgoing traffic.
How to interpret those values
You must distinguish between in-house (switched net) and WAN, furthermore the values are related to each other.
The following values are "normal" limits, but it is also possible that you have a rather good call quality with values which are ("much") higher.
It is up to the administrator to interpret this values in the context.
For example if you lose 20 packets in a two minute call, it is much more bad then losing 20 packets in a 2 hour call.
in-house connections:
(<5/0-9/-)
WAN connections:
(150/16-25/<10)
