Customizing  Your  Phone 
109 
The “$” followed by the sequence number of a parenthesis means the 
characters placed in the parenthesis. The sequence number stands for the 
corresponding parenthesis. Example: 
A replace rule configuration, Prefix: "001(xxx)45(xx)", Replace: "9001$145$2". 
When you dial out "0012354599" on your phone, the IP phone will replace the 
number with "90012354599". “$1” means 3 digits in the first parenthesis, that 
is, “235”. “$2” means 2 digits in the second parenthesis, that is, “99”. 
Note 
Replace Rule 
You can configure one or more replace rules (up to 100) to remove the specified string and 
replace it with another string. You can configure a pattern with wildcards (refer to the expression 
syntax in the table above), so that any string that matches the pattern will be replaced. This 
feature is convenient for you to dial out a long number. For example, a replace rule is configured 
as “Prefix: 1” and “Replace: 1234567”, when you try to dial out the number “1234567”, you just 
need to enter “1” on the phone and then press the Send soft key. 
To add a replace rule via web user interface: 
1.  Click on Settings->Dial Plan->Replace Rule. 
2.  Enter the string (e.g., 1) in the Prefix field. 
3.  Enter the string (e.g., 1234567) in the Replace field. 
4.  Enter the desired line ID in the Account field or leave it blank. 
 
The IP phone supports a new dial plan mechanism – digit map. Digit maps are defined by a single 
string or a list of strings. If a number you dial matches any string of a digit map, the call is 
automatically placed. 
Note that if digit map feature is enabled, the old dial plan rules (described in this chapter) will be 
ignored. For more information, contact your system administrator.
