coder is manual or automatic.
When Automatic is selected, the
local and remote voice channels will
negotiate the voice coder to be used
by selecting the highest bandwidth
coder supported by both sides
without exceeding the Max
Bandwidth setting.  G.723, G.729, or
G.711 are negotiated.

Dynamic Jitter
Dynamic
Jitter BufferDynamic Jitter defines a minimum
and a maximum jitter value for
voice communications. When
receiving voice packets from a
remote 
MultiVOIP, varying delays
between packets may occur due to
network traffic problems. This is
called Jitter. To compensate, the
MultiVOIP  uses a Dynamic Jitter
Buffer.  The Jitter Buffer enables the
MultiVOIP to...

In each field, enter the values that fit  your particular network.
The kinds of parameters for which values must be chosen depend on
the type of telephony supervisory signaling or interface used (FXO,
E&M, etc.).  We present here the various parameters grouped and
organized by interface type.
