The present disclosure provides a device including an interface. By adopting the device with a luminous part arranged at a physical interface, the problem of difficulty in accurately finding a position of the physical interface of the device in a dark environment is solved, so that a user can conveniently and rapidly identify the position and direction of the physical interface, and a user experience is improved.

A method for automatically making a telephone call associated with an event may include accessing, at a telephone, event data. The event data may include a date associated with an event, a time associated with the event, and a telephone number associated with the event. The method may also include presenting, on a display associated with the telephone, an event reminder on the date associated with the event and at the time associated with the event. The method may also include, in response to detecting an off-hook condition at the telephone while the event reminder remains presented on the display associated with the telephone, automatically calling, from the telephone, the telephone number associated with the event.

Disclosed in the present invention is a VoLTE-based voice call method. The method comprises: a calling terminal determining whether a VoLTE call mode is activated: if so, the calling terminal generating a call request, the call request comprising contact card information of the calling terminal; and the calling terminal sending the call request to the called terminal, so as to enable the called terminal to acquire the contact card information of the calling terminal from the call request. The present invention can facilitate users to exchange contact card information.

A system and method of verifying a caller identification utilizing a server that communicates with a computing device capable of monitoring communication networks for specific communications from an enterprise voice network. The server can push a spoof prevention contact list to user devices. Additionally, the server can receive notifications from the computing device in response to user inputs that allow match analysis to occur with the information in the received notifications. When a match is found, the server can send a notification to a user device to modify a contact name in the spoof prevention list stored in the user device. After a specified time, the contact name can be altered back to the original state. As an example, the contact name in the spoof prevention list may start out as “unverified call,” and be changed temporarily to “verified call” upon receipt of the notification.

A system for providing management of contact records includes a contact record that is associated with an initiator and is indexed by a phone number of the originator. To initiate delivery of some part of the contact record of the originator, the originator enters a phone number of a recipient into an application and some part of the fields of the contact record are transmitted to a device of the recipient where they are stored in the recipient's contact list. In some embodiments, the part of the fields sent is determined by a relationship between the initiator and the recipient such as family, co-worker, acquaintance, friend, stranger, etc. When changes are made to the contact record, the recipient device will receive updated information. Features are provided for automatic deletion of the subset of fields from the recipient device upon request or after a specified time period.
