dtmf sensitivity-level

Syntax dtmf sensitivity-level { high low }

undo dtmf sensitivity-level

View Analog FXS/FXO voice subscriber line view

Parameter 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.

Description Use the dtmf sensitivity-levelcommand to set the DTMF detection sensitivity level.

Use the undo dtmf sensitivity-levelcommand 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.

Example # Set the DTMF detection sensitivity level of voice subscriber line 1/0 to low.

dtmf time

Syntax	dtmf time { interval persist } milliseconds
	undo dtmf time { interval persist }
View	Voice view
Parameter	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.

Description Use the dtmf time command to configure the related time parameters of DTMF.
