Example: Adding Replace Rules Using a Replace Rule File
The following example shows the configuration for adding replace rules.
Customize the replace rule template file and place this file to the provisioning server “http://192.168.10.25”.
Example
dialplan_replace_rule.url = http://192.168.10.25/DialPlan.xml
After provisioning, the rules defined in this file are added to the IP phone, and you can use the replace rules on the
phone.
Dial Plan Defined by Digit Map (New Dial Plan Mechanism)
Digit maps, described in RFC 3435, are defined by a single string or a list of strings. If a number entered matches any
string of a digit map, the call is automatically placed. If a number entered matches no string - an impossible match -
you can specify the phone’s behavior. You can specify the digit map timeout, the period of time before the entered
number is dialed out.

Basic Regular Expression Syntax for Digit Map
You need to know the following basic regular expression syntax when creating a new dial plan:
T
The timer letter “T” indicates a timer expiry. If “T” is used alone (for example, 123T), the default timeout value of
3 will be used. If “T” is not used alone (for example, 123<Tx>, x can be a digit from 0 to 99), a complete match
occurs when waiting x seconds after inputting 123.
x
The “x” can be used as a placeholder for any digit from 0 to 9.
Example:
“12x” would match “121”, “122”, “123”, and so on.
[]
The square bracket "[]" can be used as a placeholder for a single character which matches any of a set of char-
acters. Example:
"91[5-7]1234" would match “9151234”, “9161234”, “9171234”.
- The dash “-” can be used to match a range of digits within the brackets.
