How to invite by phone while in a Zoom Rooms meeting

2. Tap Manage Participants, then tap Invite on your Zoom Room controller.
3. Tap the Phone tab.
4. Tap the number icon at the top left to select a country code if you are dialing an international number.
5. Dial a number then tap the phone icon. 
6. You can also tap the downwards arrow at the top right to view previously-dialed numbers. Tap the displayed number to dial it.

Zoom Phone 

Follow these steps if you added a Zoom Room to Zoom Phone:

1. Tap Phone in the left-side panel on the Zoom Rooms controller.
2. Use one of these methods to make a call:
   Note: The room's Zoom Phone extension number and direct phone number (if one was assigned to the room) appear in the lower-right corner. If you want to change the outbound caller ID, change the Outbound Caller ID option in the room's phone settings.
   
   • Using the dial pad, enter a number then tap the phone icon.
   • Tap the downward arrow at the top right to view previously-dialed numbers. Tap the displayed number to dial it.
   • Tap the contacts icon to view other phone users in the same organization. Tap the phone icon to call the contact.
