		seconds have elapsed if the user forgets to press the “Re-Dial” button.
		The “Yes” option should be used ONLY if there is a SIP proxy configured and the proxy
		server supports 484 Incomplete Address response. Otherwise, the call will likely be
		rejected by the proxy (with a 404 Not Found error).
		This feature does NOT work with and should NOT be enabled for direct IP-to-IP calling.
	Dial Plan Prefix	Sets the prefix added to each dialed number.
	Use # as Dial Key	Allows users to configure the “#” key as the “Send” (or “Dial”) key.		If set to “Yes”, “#”
		will send the number. In this case, this key is essentially equivalent to the “Dial” key. If
		set to “No”, this “#” key can be included as part of number.
	Dial Plan	Dial Plan Rules:
		1. Accept Digits: 1,2,3,4,5,6,7,8,9,0 , *, #, A,a,B,b,C,c,D,d
		2. Grammar: x - any digit from 0-9;
		• xx+ - at least 2 digits number;
		• xx. – at least 1 digit number.
		• ^ - exclude;
		• [3-5] - any digit of 3, 4, or 5;
		• [147] - any digit 1, 4, or 7;
		• <2=011> - replace digit 2 with 011 when dialing
		• < =1> - add a leading 1 to all numbers dialed, vice versa will remove
		a 1 from the number dialed
		• - or
		• Example 1: {[369]11 1617xxxxxxx} – Allow 311, 611, 911, and any 11 digit
		numbers with leading digits 1617
		Example 2: {^1900x+ <=1617>xxxxxxx} – Block any number of leading digits
		1900 and add prefix 1617 for any dialed 7 digit numbers
		• Example 3: {1xxx[2-9]xxxxxx <2=011>x+} –Allow any combinations of numbers
		with 11 digits which has a leading digit 1, but 5th digit cannot be 0 or 1. Or any length
		of numbers with a minimum of 2 digits beginning with 2, with the leading digit
		replaced with 011.
		3. Default: Outgoing - {x+}
		Example of a simple dial plan used in a Home/Office in the US:
		{ ^1900x. <=1617>[2-9]xxxxxx 1[2-9]xx[2-9]xxxxxx 011[2-9]x. [3469]11 }
		Explanation of example rule (reading from left to right):
		• ^1900x. - prevents dialing any number started with 1900
		• <=1617>[2-9]xxxxxx - allows dialing to local area code (617) numbers by dialing
		7 numbers and 1617 area code will be added automatically
		• 1[2-9]xx[2-9]xxxxxx - allows dialing to any US/Canada Number with 11 digits
		length
		• 011[2-9]x. - allows international calls starting with 011
		• [3469]11 - allow dialing special and emergency numbers 311, 411, 611 and 911
		Note: In some cases user wishes to dial strings such as *123 to activate voice mail or
		other application provided by service provider. In this case * should be predefined
		inside dial plan feature and the Dial Plan should be: { *x+ }.
	Subscribe for MWI	Default is No. When set to “Yes” a SUBSCRIBE for Message Waiting Indication will be
		sent periodically.
	Send Anonymous	If this parameter is set to “Yes”, the “From” header along with Privacy and P_
		Asserted_Identity headers in outgoing INVITE message will be set to anonymous,
		blocking Caller ID.
