Inviting others by phone (call out)


While in a meeting or webinar, you can call others to join the meeting or webinar by phone (also known as "call out"). 

Prerequisites for inviting others to a meeting by phone

Note: Make sure the call-out phone numbers in the account are not blocked by your phone service.  For international calling numbers, Zoom will use the numbers list in the web portal in ascending order. This means if the first number is not available, the next number on the list is used.

Note: If you are a participant, you can only call out to international numbers after the host has joined the meeting.
