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.

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. 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.

This field lets you specify the maximum bandwidth allowed
for this channel.
If coder is to be selected automatically (“Auto” setting),
then enter a value for maximum bandwidth.
AutoCall Parameters
Auto Call AutoCall The AutoCall option enables the local MultiVOIP to call a remote
MultiVOIP without the user having to dial a Phone Directory
Database number. As soon as you access the local MultiVOIP
voice/fax channel, the MultiVOIP immediately connects to the
remote MultiVOIP identified in the Phone Number box of this
option.
This function applies on a channel-by-channel basis. It would not
be appropriate for this function to be applied to a channel that
serves in a pool of available channels for general phone traffic.
This function requires an entry in the Outgoing phonebook of the
local MultiVOIP and a matched setting in the Inbound Phonebook
of the remote voip.
Phone
Number
-- Phone number used for Auto Call function or Offhook Alert Timer
function. This phone number must correspond to an entry in the
Outbound Phonebook of the local MultiVOIP and in the Inbound
Phonebook of the remote MultiVOIP (unless a gatekeeper unit is
used in the voip system).
