An Ooma Office Pro administrator can set up Dynamic Caller ID codes by following these instructions:

1. Log in to office.ooma.com as an administrator and navigate to the Settings page.
2. Click System, then navigate to the Dynamic Caller ID tab.
3. Click Add.
4. Select an unused star code (between *20 and *29), then select a corresponding caller ID to associate with that star code. You can choose from all assigned phone numbers in your Ooma Office account.
5. Click Save.

Users may now prepend the new star code to their outgoing calls to dynamically change their caller ID. If a user will be using this star code frequently, you may want to consider creating a new programmable button with this Dynamic Caller ID entry.
