MultiVOIP Quick Start Guide
The Jitter Value defines the average inter-arrival packet
deviation (in milliseconds) before the call is automatically
disconnected. Jitter is the inter-arrival packet deviation
(phase shift of digital pulses) over the transmission
medium that causes voice breakup which can be
particularly disruptive to voice communications. The
default setting is 20 milliseconds. A higher value means
that the voice transmission will be more accepting of jitter.
A lower value will be less tolerant of jitter.
Consecutive Packets Lost defines the number of
consecutive packets that are lost after which the call is
automatically disconnected. The default is 30 packets.
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.
14. You can set billing options for inbound and/or outbound
calls by checking them in the Billing Options group and
then entering the charge in cents per number of seconds.
15. A minimum and maximum set of values can be set for
Dynamic Jitter Buffer. When receiving voice packets
from a remote MultiVOIP, 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.
