			“Regional Parameter” Definitions
Field Name	Values	Description
		Name of a country or region that uses a certain set of tone pairs for dial tone, ring tone,
Country/Region	USA,
	Japan, UK,	busy tone, unobtainable tone (fast busy tone), survivability tone (tone heard briefly, 2
	Custom	seconds, after going off hook denoting survivable mode of VOIP unit), re‐order tone (a tone
		pattern indicating the need for the user to hang up the phone), and intercept tone (a tone
		that warns an a party that has gone off hook but has not begun dialing, within a prescribed
		time, that an automatic emergency or attendant number is called; the automatic call can be
		used to direct an attendant’s attention to a disabled or distressed caller, allowing an
		appropriate response to be made).
		In some cases, the tone‐pair scheme denoted by a country name may also be used outside
		of that country. The “Custom” option (button) assures that any tone‐pairing scheme
		worldwide can be accommodated.
		Note 1: Intercept tone is applicable only when the FXS telephony interface has been chosen
		in the Interface window and when the AutoCall / OffHook Alert field is set to OffHook Alert
		in the Voice/Fax Parameters window. The time allowed for dialing before the automatic
		calling process begins is set in the OffHook Alert Timer field of the Voice/Fax Parameters
		window.
		Note 2: “Survivability” tone indicates a special type of call‐routing redundancy and applies
		to MultiVantage VOIP units only
Advisory window					This message appears when the Country field is
					changed. It informs the operator that, when the
					Country field changes, user defined tones are deleted.
