dtmf sensitivity-level { high | low }
undo dtmf sensitivity-level
Analog FXS/FXO voice subscriber line view
high: Sets the DTMF detection sensitivity high. In this mode, the reliability is low
and detection errors may occur.
low: Sets the DTMF detection sensitivity low. In this mode, the reliability is high,
but DTMF undetection may occur.
Use the dtmf sensitivity-level
level.
Use the
undo dtmf sensitivity-level
sensitivity level.
By default, the DTMF detection sensitivity level is high.
This command is valid only for FXS/FXO interfaces.
# Set the DTMF detection sensitivity level of voice subscriber line 1/0 to low.

dtmf time { interval | persist } milliseconds
undo dtmf time { interval | persist }
Voice view
persist: Specifies the persisting time of sending DTMF.
Interval: Specifies the interval for sending DTMF.
milliseconds: Time in milliseconds, in the range of 50 to 500.
Use the dtmf time
command to set the DTMF detection sensitivity
command to restore the default detection
command to configure the related time parameters of DTMF.
