Grandstream Networks GXW40XX user manual Early Dial, Dial Plan Prefix, Use # as Dial Key

Early Dial	Default is No.	Use only if proxy supports 484 response. This parameter controls
	whether the phone will send an early INVITE each time a key is pressed when a user
	dials a number. If set to “Yes”, an INVITE is sent using the dial-number collected thus
	far; Otherwise, no INVITE is sent until the “(Re-)Dial” button is pressed or after about 5
	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 is NOT designed to 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.

•Example 1: {[369]11 1617xxxxxxx} –

Allow 311, 611, 911, and any 10 digit numbers of 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 length of number with leading digit 2 and 10 digit-numbers of leading digit 1 and leading exchange number between 2 and 9; If leading digit is 2, replace leading digit 2 with 011 before dialing.

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 will be: { [x*]+ }.
