I successfully developed an app using server-to-server authentication, and it worked perfectly. However, when I tried calling the API endpoint https://api.zoom.us/v2/phone/users/v8jyG2uYT3akHAcG3XsfTQ/sms/sessions, I received the following error:
{
"code": 2031,
"message": "Zoom Phone has not been enabled for this account."
}
Although my account was previously on a Basic plan, I have now attached the necessary license. Despite this, the error persists.
