Updated phone information

Where do I control what phone number is visible to guests for communication on Owner Rez? Will this update automatically in AirBNB and VRBO if I have integration?

You can change this in your Profile. That's in the dropdown-arrow menu in the upper right corner of the OR screen. It should be automatically used throughout OwnerRez if you are using the field codes correctly.

I'm not sure about the APIs though, since you have to have your own accounts with those companies.
