Call Duration defines the maximum length of time (in seconds) that a call remains
connected before the call is automatically disconnected. The default setting is 180 seconds.
A call limit of three minutes may be too short for most configurations. Therefore, you may
want to increase this default value.

A minimum and maximum set of values can be set for Dynamic Jitter Buffer. When
receiving voice packets from a remote MVP120, it is possible to experience varying delays
between packets due to traffic conditions on the network. This is called Jitter. To compensate
for this effect, the MVP120 uses a Dynamic Jitter Buffer. The Jitter Buffer allows the MVP120
to wait for delayed voice packets by automatically adjusting the length of the Jitter Buffer
between configurable minimum and maximum values. An Optimization Factor adjustment
controls how quickly the length of the Jitter Buffer is increased when jitter increases on the
network. The length of the jitter buffer directly effects the voice delay between MVP120
gateways.
The Minimum Jitter Value default setting is 150 milliseconds, the Maximum Jitter Value
default setting is 300 milliseconds, and the Optimization Factor default setting is 7.
