Inviting others by phone (call out)

Last Updated:

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 US numbers, Zoom will always use this dedicated number, +1-646-568-7788. 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. If none of the numbers with the respected country are available, Zoom will use the US dedicated number, +1-646-568-7788.

How to invite participants to a meeting using the call out feature

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

  1. Sign in to the Zoom Desktop Client.
  2. Start or join a meeting.
  3. Click Participants in the meeting controls.
  4. Click Invite at the bottom of the participants panel.
  5. Click the Call Out tab and specify the following information
    • Invitee name: Enter a display name for the invitee to display to other participants.
    • Country/Region: Select the country code of the invitee's phone number.
    • Phone Number: Enter the invitee's phone number.
      Note: If you are dialing a phone number that includes an extension, type a hyphen "-" after the phone number and enter the extension. For example, 6032331333-156 dials the extension 156.
    • Invite Options
      • Require greeting before being connected: Play a generic greeting before the invitee joins the meeting.
      • Require pressing 1 before being connected: Prompt the invitee to press 1 before they can join the meeting.
        Note: These options are both required. Contact Zoom if you need to modify or disable these options.
