Early Dial
Selects whether or not to enable early dial. If set to "Yes", the SIP proxy must
support 484 responses. Early Dial means that the phone sends for each
pressed digit a SIP INVITE message to SIP server. SIP server looks into its
extensions and, if no match happened yet, it sends back a "484 Address
Incomplete" message. Otherwise, it executes the action. Default setting is "No".
Dial Plan Prefix
Configures the prefix to be added to each dialed number.
Dial Plan
A dial plan establishes the expected number and pattern of digits for a
telephone number. This parameter configures the allowed dial plan for the
phone. Default setting is “{ x+ | \+x+ | *x+ | *xx*x+ }”.
Dial Plan Rules:
1. Accepted 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
X – digits from 0-9, and letters from a-z, A-Z.
a) xx+ - at least 2 digit numbers
b) xx - only 2 digit numbers
c) ^ - exclude
d) [3-5] - any digit of 3, 4, or 5
e) [147] - any digit of 1, 4, or 7
f) <2=011> - replace digit 2 with 011 when dialing
g) | - the OR operand
h) {X123} - match Z123, e123, 5123, …
i) Back slash “\” Character can be used to escape specific letters. e.g.
if { \p\a\r\k\+60 } dial plan is configured, park+60 should be able to pass
dial plan check. This also can be used to escape Mark and User-
unreserved characters.
Mark = "-" / "_" / "." / "!" / "~" / "*" / "'" / "(" / ")"
User-unreserved = "&" / "=" / "+" / "$" / "," / ";" / "?" / "/"
• Example 1: {[369]11 | 1617xxxxxxx}
Allow 311, 611, and 911 or any 10 digit numbers with leading digits 1617;
• Example 2: {^1900x+ | <=1617>xxxxxxx}
Block any number of leading digits 1900 or add prefix 1617 for any dialed 7 digit
numbers;
• Example 3: {1xxx[2-9]xxxxxx | <2=011>x+}
Allows any number with leading digit 1 followed by a 3 digit number, followed by
any number between 2 and 9, followed by any 7 digit number OR Allows any
length of numbers with leading digit 2, replacing the 2 with 011 when dialed.
• Example 4: If we set the dial plan with {\*123}, it should allow input *123 to
pass dial plan check.
