	Frequency 1	freq. in Hertz	Lower frequency of pair.
	Frequency 2	freq. in Hertz	Higher frequency of pair.
	“Regional Parameter” Definitions (cont’d)
	Field Name	Values	Description
	Standard Tones fields (cont’d)
	Cadence	n/n/n/n	On/off pattern of tone durations
	(msec) On/Off	four integer time	used to denote phone ringing,
		values in	phone busy, connection
		milli-seconds;	unobtainable (fast busy), dial tone
		zero value for	(“0” indicates continuous tone),
		dial-tone	survivability, and re-order. Default
		indicates	values differ for different
		continuous tone	countries/regions. Although most
			cadences have only two parts (an
			“on” duration and an “off”
			duration), some telephony
			cadences have four parts. Most
			cadences, then, are expressed as
			two iterations of a two-part
			sequence. Although this is
			redundant, it is necessary to allow
			for expression of 4-part cadences.
	Gain 1	gain in dB	Amplification factor of lower
		+3dB to –31dB	frequency of pair.
		and “mute”	This applies to the dial, ring, busy
		setting	and ‘unobtainable’ tones that the
			MultiVOIP outputs as audio to the
			FXS or FX0 port. Default: -16dB
	Gain 2	gain in dB	Amplification factor of higher
		+3dB to –31dB	frequency of pair.
		and “mute”	This applies to the dial, ring, busy,
		setting	and ‘unobtainable’ (fast busy) tones
			that the MultiVOIP outputs as
			audio to the FXS or FXO port.
			Default: -16dB
