Zoom Phone Smart Embed not working with error “Unable to sign in”

Can I use Phone Smart Embed even if the administrator has a basic license?

管理者がベーシックライセンスの場合でも、Phone Smart Embedは利用できるでしょうか?

Hi @shinichi
Thanks for reaching out to us and welcome to the Zoom developer forum
In order to be able to use the Zoom Phone Smart embed, you must have a Phone license added to your Zoom Account.

Here is a helpful blog that describes how to get started with it!
