I Receive Error 4016 when I Try to Join a Webex Teleconference

To resolve issue related to not having Global Call-in permissions enabled in a host account.

I receive error 4016 when I try to join a Webex teleconference.

Error 4016 when I dial into a global teleconference number.

Attendees are unable to join the Webex teleconference when they use global teleconference numbers.

Cause:

This error may occur due to the following reasons:

  • The host does not have the 'Allow access to teleconference via global call-in numbers' option enabled for their host account, and an international teleconference number is dialed.
  • This error can also be caused if the host has the permissions to use toll-free numbers, but the "Display toll-free number" option is not enabled in the Audio Conference settings of a particular meeting. If an attendee then attempts to call a toll-free number which appears on the "All global call-in numbers" list when joining a meeting.
    • Note: Attendees may still join the teleconference if they dial into the toll number displayed on the audio conference dialog.
  • The Webex Personal Conferencing (PCN) account was created before Global call in teleconferencing was enabled on the site.

Solution:

Join the meeting to determine if 'Allow access to teleconference via global call-in numbers' is disabled. If call-in numbers are only displayed for a single country, then global call-in is disabled.

Note: Global call-in cannot be enabled from within the meeting.

To create a new meeting with global call-in capability:

  1. Go to the Webex Meetings tab, then click Schedule a Meeting.
  2. Click the Change audio conference... link.
  3. Check the box for Display global call-in numbers.
  4. Complete the scheduling process.

If 'Display global call-in numbers' or 'Allow access to teleconference via global call-in numbers' option isn't present, a site admin can use the following steps to enable this option.

Site Administrators Only

To confirm if the host account has access to global teleconference numbers:

  1. Log in to your Webex Site Administration page. (Example: https://SITENAME.Webex.com/admin.php)
  2. On the Site Administration home page, confirm there is a green check mark beside Global call-in.



    Note: If there is no check mark beside this feature, global call-in is not enabled on the site. Contact your CSM for further assistance, see:
    WBX15 - How Do I Contact My Customer Success Manager (CSM)?
  3. Click on User Management in the left navigation bar.
  4. Click Edit User.
  5. Enter your search criteria into the User name: or Email: field, then click Search.
  6. Click the name of the account that needs to be modified.
  7. In the Telephony privilege: section, confirm the Allow access to teleconference via global call-in numbers option is checked.
Note: If you are using a Webex personal conferencing account that was created before global call-in was enabled on the site. You must create a new account to resolve this issue, see: Schedule a Personal Conference or Audio Only Webex Meeting
