Setting up shared line groups Follow

A shared line group allows Zoom Phone admins to share a phone number and extension with a group of phone users or common area phones. All members of the shared line group has access to the group's direct phone number and voicemail. You can apply custom business, closed, and holiday hours to shared line groups and set routing rules. If you aren't sure that shared line groups fits your use case, see our comparison of call routing methods.

The following terms are used in this article:

  • Members are added to the shared line group by your Zoom Phone admin. Each member can only belong to one shared line group. If you enabled multiple sites, members don't need to belong to the same site as the shared line group.
  • Shared lines are direct phone numbers that are assigned to the shared line group and shared among its members.

Note: Provisioned desk phones assigned to members will reboot several times when you set up a share line group or change its settings.

After setup, members can use shared line groups on the Zoom desktop client / mobile app or a desk phone. You can also enable call monitoring for shared line groups and change shared line group settings.
