Audio Inputs and Outputs
What is Audio I/O?
The Audio I/O ports are routing objects that cooperate with the audio ports of the
Audio/IO/Relay board. Sounds enter the PBX or are played back through these inputs.
The inputs can be used as a source of external progress tones and the outputs as a
broadcast, for example.
Audio Ports
The Audio/IO/Relay board can be equipped with two or four stereo jack ports with the
diameter of 3.5 mm, which represents four or eight ports (each stereo port is used as
two mono ports). No port can be used as an input and output at the same time. Define
the attenuation value for each port ranging from –70 to 70 dB.
The audio ports cannot be used as standard PBX virtual ports and should be assigned
to a specific routing object of the Audio I/O type. Each audio port can be assigned to
multiple Audio I/O routing objects.
Audio I/O Setting
The menu for the Audio I/O routing objects is divided into two parts. You can add,
delete or rename the routing objects on the left and define a selected object on the
right using the following parameters.
Name – displays the name of a selected routing object only. It cannot be directly
configured here.
Audio I/O – assigns a selected Audio/IO/Relay board source to an object.
Cancelled by incoming call – is a radio function option (has not been
implemented yet). If a call comes during radio playing, the radio function is
terminated and the terminal starts ringing. If this option is not checked, the
incoming call is rejected with the user busy cause (or queued).
Turn on tone to caller – enables playing of the below–defined tone to the
calling user. The calling user should always hear the tone. It means that you
cannot play a tone to the assigned source only but you can disable tone playing
for both directions.
Turn on tone to Audio I/O – enables playing of the below–defined tone to a
selected Audio/IO/Relay board source.
Tone – defines the tone to be played to the calling party or/and to the selected
Audio/IO/Relay source.
Turn off tone after a time limit – enables the tone time limit. If the time
parameter is switched off, the whole tone is always played back. After the tone
has been played, the calling user is connected to the assigned source for
broadcasting.
Tone time [ms] – use this parameter to define the tone playing time. It may be
shorter or longer. After this period, the calling user is connected to the assigned
source for broadcasting.
