microphone audio when the channel is active. If IFB mode for the channel is
enabled and the AoIP source is an available intercom device, but the
configured IFB stream does not exists, a non IFB mode call will be
connected instead. This option is unavailable when the connection type is
set to Audio IO 3.
IFB Source
– This is the AoIP stream name prefix of the IFB stream on the
selected AoIP Source. This name can be entered manually, or it can be
selected from the dynamic list of available IFB sources detailed below. This
option is only available if IFB mode is enabled.
Available IFB Sources
– This dynamic drop down list shows the names of
the available IFB streams on the selected AoIP source. If the selected AoIP
source is not an IFB enabled intercom device, this list will be empty. This
option is only available if IFB mode is enabled.
Auto Answer
– This op�on allows an incoming call on the selected channel
to be answered automa�cally without the need to press the associated
channel bu�on.
Default Function
– The default function option sets the call type that is
initiated when the corresponding channel button is pressed. Talk & Listen
calls allow both the caller and receiver hear each other. In a Talk Only call,
only the receiver hears the caller. In a Listen Only call, only the caller hears
the receiver. Talk Forced Listen calls allow the caller to hear the receiver,
with the option to enable or disable talk to the receiver by repeatedly
pressing the channel button. If IFB mode is enabled on the selected
channel, Talk Forced Listen is not available. The default function can be
overridden when initiating call by using the listen button on the front panel.
Button Mode
– Selects the opera�onal mode of the selected channel talk
bu�on. In momentary mode, the channel is ac�ve whilst the bu�on is
pressed. In latching mode, a separate bu�on press is required to enable and
disable the channel. In auto mode, the bu�on has a momentary ac�on that
will automa�cally latch on or off if pressed briefly. The bu�on can also be
disabled if required. Momentary mode is not available if auto answer is
enabled.
Call Signal
– This op�on enables an audible indica�on that an incoming call
is wai�ng to be answered. The call signal is heard through the loudspeaker,
or the headphones if connected. This se�ng applies to all channels.
