Assign Contacts permission to an IP phone

To query and use Contacts on an IP phone, you should assign Contacts permission to the IP phone via PBX's Auto Provisioning.

  • To display company contacts on an IP phone, you need to configure Company Contacts permissions for the user.
  • If you change user's permission of viewing company contacts, you should go to Auto Provisioning App to update IP phone settings, or the permission change will not take effect.


  1. Log in PBX web page, and go to Auto Provisioning App.
  2. On Device List page, select an IP phone and click .
    Note: If multiple accounts are registered on an IP phone, the IP phone can only obtain the first account's Contacts.
