Figure 5-2 Audio setting
RFC 2833 Payload Type: 96 or 101. It is recommended to use 101.
DTMF Send On Time(msec): When generate DTMF, the DTMF on
time will be sent (default time is 70 ms)
DTMF Send Off Time(msec): When generate DTMF, the DTMF OFF
time between two digits will be sent (default time is 70 ms)
DTMF Detect Min on Time (msec): The minimum DTMF ON time
will be recognized as a regular DTMF event. Less than this time will be
ignored. The default value is 60ms.
DTMF Detect Min off Time (msec): The minimum DTMF OFF time
between two digits to recognize. Less than this time, the next DTMF
digit will be recognized as the same previous one. It will be handled as
one digit only instead of two digits.
DTMF Relay Volume: The DTMF relay volume in dBm.
Min Jitter Buffer (msec): The minimum delay time of Jitter buffer.
Max Jitter Buffer (msec): The Maximum delay time of Jitter buffer.
Max Echo Tail Length (G.168): Enable the echo cancellation
feature. The default setting is 128ms.
Jitter Opt. Factor: Jitter buffer dynamic factor for optimize. Please
set to 7 unless under Welltech’s instruction to change.
