Prerequisites Base License: Fax Add-on License: Number (only 1 add-on per base license) Access Control Owner: Admins: Members: Permission Management

While the utilization of traditional fax machines has significantly diminished, many large enterprises continue to incorporate faxing as an integral component of their corporate infrastructure.

Although modern fax machines now support advanced features like fax-to-email and vice versa, our emphasis in developing a fax solution centers on optimizing the fax-to-email functionality.

This approach caters to the evolving needs of enterprises, allowing for seamless integration with contemporary communication systems while addressing the occasional necessity for faxing within a corporate environment.

Prerequisites

Base License: Fax

Add-on License: Number (only 1 add-on per base license)

 

Access Control

With Permission V2, access is managed by role and by the selected fax account.

  • Owner: has full access to all fax accounts and settings.
  • Fax Admin: can view, edit and manage access to fax accounts. Admins with access through the legacy Fax Permission Group are migrated to this role.
  • Assigned users: Admins and Members can be assigned to specific fax accounts. Existing access to specific fax numbers is retained during migration.

To assign or remove users, you must be the Owner or have permission to manage access for the selected fax account. Viewing a fax account does not by itself grant permission to manage other users.

Assign a user to a fax account

  1. Open Fax on the portal.
  2. Select Account and open the fax number.
  3. Beside Assigned users, select the edit icon.
  4. In Assign user, use Select user to find and select an Admin or Member.
  5. Select Assign.
  6. Check that the user appears in the assigned-user list.

You can assign up to 50 users to a fax account.

Remove access

  1. Open the edit dialog beside Assigned users.
  2. Remove the user from the selected list.
  3. Select Assign to save.

Removing the user revokes their assigned access to that fax account.

Use Assigned users to grant or remove access to the selected fax account.
Use Assigned users to grant or remove access to the selected fax account.

For account information, access management and email settings, see CPaaS Fax — Account.
