Goodmorning,

I’m trying to create a report using Zoom’s data collected through API. The data that I collected shows that most of the inbound calls were not answered but when I check on the Built-in reports in Zoom they show that only a few calls were missed. How does zoom determine if a call was missed or answered?

Hi @Mark15 confirming you are to Zoom Phone calls?

When you say data you collected, was that via API? Which specific endpoint please?

Yes it was via API.

GET /phone/users/{userId}/call\_history
