CONFIGURATION ITEMS
Item Description
Sampling rate The can only sample audio at one frequency
for all ports. The available frequencies are
8kHz, 16kHz and 32kHz. A larger sampling
frequency will provide better audio quality at
the cost of more bandwidth.
Enable Port Enables the port if checked.
Server IP Only enabled if the is in client mode. It con-
tains the address of the server to which this
specific channel should connect.
Server VoIP Port Only enabled if the VoICE unit is in client
mode. It contains the IP port of the VoICE
server to which this specific channel should
connect. The default is 4569 for all channels.
It needs to match the port in the configura-
tion/advanced tab of the VoICE server.
Remote Port Only enabled if theVoICE unit is in client
mode. This represent the physical port of the
VoICE server to which this port should con-
nect to. For instance, it is possible to connect
client port 1 to server port 2.
Silence Suppress
Enabled Enables suppression of silence in transmit
mode. This option will significantly reduce the
bandwidth usage.
Network Jitter Min Amount of minimum buffer time.
Network Jitter Max Amount of maximum buffer time. Reducing
the maximum jitter buffer size will reduce
overall delay but might cause audio packet
loss.
Echo Tail This time is the window within which the echo
is cancelled. A value of zero (0) disables the
echo cancel feature. The recommended echo
tail value is approximately the third of the
room reverberation time. For example, in a
small room, reverberation time is in the order
of 300 ms, so a tail length of 100 ms is a good
choice.
Noise Filter Enable Enables suppression of background noise if
checked.
