Click Next Stream to configure the first audio stream with default algorithm, jitter and FEC
settings which are physically entered in the codec. Alternatively, click Next to specify
individual algorithm, jitter buffer and FEC settings and configure a failover connection or

For IP connections click to configure:
· Auto Jitter Adapt and the preferred auto jitter setting using the drop-down arrow for
Buffer priority. It is also possible to configure the Minimum depth and Maximum
depth of jitter over the connection. See
· Alternatively, select a Fixed Buffer Level and enter the Jitter Depth, which must be
between 12ms and 5000ms depending on the algorithm you select.
· Local and Remote FEC settings if required.
Important Notes:

delay the sending of FEC packets for a predetermined period after the primary audio
stream's packets are sent. This will increase the likelihood that the FEC packets will
take an alternate route to the primary stream's packets. This means that if primary
audio stream packets are not received at the remote codec, there is a good chance
that FEC packets taking an alternate route will be received and replace them. When
a FEC percentage lower than 100% is configured, FEC packets are automatically
