Zoom allows you to sign in to one computer, one tablet, and one phone at the same time.

If you sign in to a second device of the same type, you will be signed out automatically from the first device of that type.

For example, if you are already signed in to a Windows desktop, and you are also trying to sign in to a Windows laptop at the same time, you will be signed out of the desktop.

Launch your Zoom desktop client or mobile client. If you see the Phone icon in the main screen, you can start using Zoom Phone.

Yes, you can. Download and install the Zoom app from iOS App Store (for iPhone/iPad) or Google Play Store (for Android) and you can Zoom Phone within the app.

Your colleagues can only call your Zoom extension number from another Zoom extension. Calls cannot be made from Teams to Zoom Phone or vice versa.

For internal/external calls. For staff who needs to make external calls, the department phone admin would raise a BOSS request for a DID number and the staff Zoom Phone will be updated with a 8-digit number.
