Click the New Rule to open the rule creation window.
Enter a Name for the rule.
Select a Condition for the rule. A dialog box will appear where you may specify the details of the condition and the alternate phone number or transfer number you want Outlook to provide to callers. Outlook will play a text-to-speech recording for your callers of the text you type in this field.
NOTE: As you define actions, be sure to assign different numbers for your callers to press for each action, or the system won't be able to offer the action as an option.
