Not all phones are enabled to make long distance and/or international calls. Please contact your department's authorized user to change your permissions. The authorized user can fill out the Change Request form. Cisco VoIP Request Forms

When you block caller ID, you are only blocking caller ID for that call. Any subsequent calls will not block unless you dial the 1 * 67 first.
