At most 100 replace rules can be added to the IP phone.

The expression syntax in the replace rule template is the same as that introduced in
the section Dial Plan
To customize a replace rule template:
1. Open the template file using an ASCII editor.
2. Create replace rules between <DialRule> and </DialRule>.
For example:
<Data Prefix="2512" Replace="05922512" LineID="1" />
Where:
Prefix="" specifies the numbers to be replaced.
Replace="" specifies the alternate string instead of what the user enters.
LineID="" specifies the desired line(s) for this rule. When you leave it blank or enter 0,
this replace rule will apply to all lines.
If you want to change the replace rule, specify the values within double quotes.
3. Save the change and place this file to the provisioning server.
4. Specify the access URL of the replace rule template in the configuration files.
Procedure
Specify the access URL of the replace rule template using configuration files.
