Zoom will use the list of international phone numbers in the web portal in ascending order whenever international numbers are to be called. Therefore, it means that if the first number on the list is not available, the second number on the list will be used instead. You should also verify that your phone service has not blocked the phone numbers for the call-outs in your account. Zoom will always use the following dedicated number for US-based numbers, +1-64.

Make sure your meeting or webinar role has permission to use call-out to join audio by phone or invite others.

Setting is enabled at the account, group, or user level.

Prerequisites for joining meeting or webinar audio by phone

It is also not possible to use the “Call me” feature if the meeting is set to have “No Fixed Time.”.

It is not possible to “Call me” more than 15 minutes before the start of the meeting if you call earlier.

If you’ve joined the meeting before the host, you might be shown a holding screen until they join and start the meeting. Assuming you’re joining a UK call with a UK phone number, you will be charged your normal call rate with no extra fees. Calling into a meeting is simple: just dial the number you were given and enter the Meeting ID when prompted. If you can join by dialling in, the organiser will have sent you the Meeting ID and number to call when they invited you. Dialling in with mobile should be saved as a last resort, especially as some meetings may not support it.

This makes it a better experience for everyone and will allow you to view any resources being shared in the call, such as a presentation. It’s always best to try and join a meeting online using the Zoom app on your computer or smartphone/tablet if possible. You can’t join in browser on tablets or smartphones. If you haven’t downloaded the app you'll be automatically taken to a webpage asking you to download it. When asked what you’d like to open the link with select 'Zoom'.
