Grandstream Networks HT704 No Key Entry Timeout, Early Dial, Dial Plan Prefix, Use # as Dial Key

No Key Entry Timeout	Default is 4 seconds. Dialing process is completed and outgoing call is initiated if no
	key entry occurs during this preconfigured interval.
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 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	Default is Yes. It 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.

∙[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+ }.
