The expression syntax in the dial-now rule template is the same as that introduced in the
section Dial Plan
To customize a dial-now template:
1. Open the template file using an ASCII editor.
2. Create dial-now rules between <DialNow> and </DialNow>.
For example:
<Data DialNowRule="1001" LineID="0" />
Where:
DialNowRule="" specifies the dial-now rule.
LineID="" specifies the desired line(s) for this rule. When you leave it blank or enter 0,
this dial-now rule will apply to all lines.
If you want to change the dial-now 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 dial-now template.
