Manual or
Auto-matic Determines whether selection of 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.

kbps Select from a range of coders with
specific bandwidths. The higher the bps
rate, the more bandwidth is used. The
channel that you are calling must have
the same voice coder selected.
Default = G.723.1 @ 6.3 kbps, as
required for H.323. Here 64K of
digital voice are compressed to 6.3K,
allowing several simultaneous
conversations over the same bandwidth
that would otherwise carry only one.
To make selections from the Selected
Coder drop-down list, the Manual
option must be enabled.

kbps This drop-down list enables you to
select the maximum bandwidth allowed
for this channel. The Max Bandwidth
drop-down list is enabled only if the
Coder is set to Automatic.
If coder is to be selected automatically
(“Auto” setting), then enter a value for
maximum bandwidth.
