ip rtp quality-monitoring history
Use the ip rtp quality-monitoring history commands to configure the call history storage for voice
quality monitoring (VQM). You can use this command variations to configure the size of the call history
and to specify the thresholds used to decide when calls are stored in the call history. Using the no forms of
these commands return the call history parameters to the default settings. Variations of this command
include:
ip rtp quality-monitoring history cq-mos <value>
ip rtp quality-monitoring history jitter <value>
ip rtp quality-monitoring history loss <value>
ip rtp quality-monitoring history lq-mos <value>
ip rtp quality-monitoring history max-streams <number>
ip rtp quality-monitoring history out-of-order <value>
ip rtp quality-monitoring history pq-mos <value>
Syntax Description
cq-mos <value>
jitter <value>
loss <value>
lq-mos <value>
max-streams <number>
out-of-order <value>
pq-mos <value>
Default Values
By default, the maximum number of RTP streams allowed in the history is 100.
Setting the size of the call history to a large number can result in the AOS unit running out
of memory.
By default, MOS thresholds are set to 4.4, and jitter, loss, and out-of-order packet thresholds are set to 0.
60000CRG0-35E
Specifies a threshold for the conversational quality (CQ) mean opinion
score (MOS), and stores statistics below this threshold. The range is 0 to
4.4.
Specifies a threshold for the jitter. Statistics above this threshold are stored
as jitter. The packet-to-packet delay variation is measured in milliseconds
(from nAvgPDV). The range is 0 to 30000.
Specifies a threshold for loss (in packets). Statistics above this threshold is
stored as lost packets. The range is 0 to 30000.
Specifies a threshold for the listening quality (LQ) MOS, and stores statistics
below this threshold. The range is 0 to 4.4.
Specifies a number of previously completed call statistics to store. This is a
count of Realtime Transport Protocol (RTP) streams; each call can contain
two RTP streams. The range is 0 to 2000.
Specifies a threshold for out-of-order packets to be logged. Statistics above
this threshold are stored. The range is 0 to 30000.
Specifies a threshold for LQ MOS normalized to the PESQ (PQ) scale, and
stores statistics below this threshold. The range is 0 to 4.4.
