After the RC download from the EDOS server completes, you can view the customization state of a phone
using the web interface.
Here are the descriptions of the remote customization states:

Description
Estimated average RTP packet jitter (dynamic delay
that a packet encounters when going through the
network), in milliseconds, that was observed since
the receiving voice stream opened.
Maximum jitter, in milliseconds, that was observed
since the receiving voice stream opened.
Number of RTP packets in the receiving voice stream
that were discarded (bad packets, too late, and so on).
The phone discards payload type 19
Note
comfort noise packets that Cisco Gateways
generate, because they increment this
counter.
Missing RTP packets (lost in transit).
Total number of concealment frames divided by total
number of speech frames that were received from start
of the voice stream.
Ratio of concealment frames to speech frames in
preceding 3-second interval of active speech. If using
voice activity detection (VAD), a longer interval might
be required to accumulate 3 seconds of active speech.
Highest interval concealment ratio from start of the
voice stream.
Number of seconds that have concealment events (lost
frames) from the start of the voice stream (includes
severely concealed seconds).
Number of seconds that have more than 5 percent
concealment events (lost frames) from the start of the
voice stream.
Estimate of the network latency, expressed in
milliseconds. Represents a running average of the
round-trip delay, measured when RTCP receiver
report blocks are received.
