This section describes configuration items for the tone resources available in the phone.

4.6.1.5.1 Dual Tone Multi-Frequency <DTMF/>

Attribute	Permitted	Default	Interpretation
	Values
tone.dtmf.level	-33 to -3	-15	Level of the high frequency compo-
			nent of the DTMF digit measured in
			dBm0; the low frequency tone will
			be two dB lower.
tone.dtmf.onTime	positive	50	When a sequence of DTMF tones is
	integer		played out automatically, this is the
			length of time in milliseconds the
			tones will be generated for; this is
			also the minimum time the tone will
			be played for when dialing manually
			(even if key press is shorter).
tone.dtmf.offTime	positive	50	When a sequence of DTMF tones is
	integer		played out automatically, this is the
			length of time in milliseconds the
			phone will pause between digits;
			this is also the minimum inter-digit
			time when dialing manually.
tone.dtmf.chassis.masking	0, 1	0	If set to 1, DTMF tones will be sub-
			stituted with a non-DTMF pacifier
			tone when dialing in hands-free
			mode. This prevents DTMF digits
			being broadcast to other surrounding
			telephony devices or being inadvert-
			ently transmitted in-band due to
			local acoustic echo.
			Note: tone.dtmf.chassis.masking
			should only be enabled when
			tone.dtmf.viaRtp is disabled.
