dtmf sensitivity-level { high | low }

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 command to set the DTMF detection sensitivity 
level.

Use the undo dtmf sensitivity-level command to restore the default detection 
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.
