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+}
Allow 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 allow any length of numbers with leading
digit 2, replacing the 2 with 011 when dialed.
Example 4: {0,x+}
If user dials 0 second dial tone will be played, and users can continue entering digits. For
instance, if pressing 01234, after pressing 0 second dial tone is played, full number is sent in
INVITE.
3. Default: Outgoing – { x+ | +x+ | *x+ | *xx*x+ }
Allow any number of digits, OR any number with a leading +, OR any number with a leading *, OR
any number with a leading * followed by a 2 digits number and a *. To dial + from keypad, press

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 – allow 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 |- allow dialing to any US/Canada Number with 11 digits length
● 011[2-9]x. – allow international calls starting with 011
● [3469]11 – allow dialing special and emergency numbers 311, 411, 611 and 911
Note: In some cases, where the user wishes to dial strings such as *123 to activate voice mail or
other applications provided by their service provider, the * should be predefined inside the dial
plan feature. An example dial plan will be: {*x+} which allows the user to dial * followed by any
length of numbers.
