Description
The minimum dynamic jitter buffer of 60 milliseconds is
the minimum delay that would be acceptable over a low
jitter network.
Default = 150 msec
The maximum dynamic jitter buffer of 400 milliseconds is
the maximum delay tolerable over a high jitter network.
Default = 300 msec
The Optimization Factor determines how quickly the
length of the Dynamic Jitter Buffer is changed based on
actural jitter encountered on the network. Selecting the
minimum value of 0 means low voice delay is desired,
but increases the possibility of jitter induced voice quality
problems. Selecting the maximum value of 12 means
highest voice qauality under jitter conditions is desired at
the cost of increased voice delay.
Default = 7.
The Automatic Disconnection group provides four
options which can be used singly or in any combination.
The Jitter Value defines the average inter-arrival packet
deviation (in milliseconds) before the call is automatically
disconnected. The default is 300 milliseconds. A higher
value means voice transmission will be more accepting of
jitter. A lower value is less tolerant of jitter.
Inactive by default. When active, default = 300 ms.
However, value must equal or exceed Dynamic
Minimum Jitter Value.
Call Duration defines the maximum length of time (in
seconds) that a call remains connected before the call is
automatically disconnected.
Inactive by default.
When active, default = 180 sec.
This may be too short for most configurations, requiring
upward adjustment.
Consecutive Packets Lost defines the number of
consecutive packets that are lost after which the call is
automatically disconnected.
Inactive by default.
When active, default = 30
Specifies how long to wait before disconnecting the call
when IP network connectivity with the remote site has
been lost.
