 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 using XML Template Files on page 300.
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.
