If you want to use Roezan's native Zoom integration for webinar reminders, you'll need to update Zoom's registration fields to allow for phone numbers.
This is important because this is where Roezan will be pulling the phone numbers from to send the messages.
In Zoom, go to Webinars > Select your webinar
Scroll down to "Registration Settings" and click the edit link on the right-hand side:
Select Phone to allow phone numbers upon registration and click Save:
Make sure to test your registration process to ensure that phone numbers are being passed correctly into Zoom.

Scroll to the bottom under Manage Attendees and click edit
Select your test registration:

If the phone number is not appearing, then the contact will NOT be passed to Roezan.
