The IP phone provides a user interface for inputting ID information and password information, and when the sender inputs ID information and password information, the IP phone transmits the input ID information and password information to the cloud server. Accordingly, the cloud server confirms that the authentication procedure of the received ID information and password information is valid, and allows access for communication with the IP phone. Accordingly, the IP phone transmits its IP phone number to the cloud server.

After step S204, the cloud server matches and stores the transmitted IP phone number with the registration information of the caller terminal (step S206). The cloud server matches and stores the received IP phone number with registration information including phone number information or MAC address information of the caller terminal. Thereafter, the cloud server transmits registration processing information for an IP phone number stored in matching with the registration information of the caller terminal to the caller terminal. Accordingly, the caller terminal displays the registration processing information on the display screen. After that, the cloud server periodically or aperiodically exchanges status information on whether access is possible with the IP phone.

When the cloud server receives the receiver's phone number from the caller's terminal, it searches for registration information corresponding to the caller's terminal, and searches for an IP phone number for the stored IP phone matching the searched registration information. Then, the cloud server transmits the recipient's phone number to the IP phone corresponding to the searched IP phone number. Thereafter, the cloud server transmits to the sender terminal a notification message indicating that the recipient's phone number has been normally transmitted to the IP phone.

After step S210, the IP phone switches to an OFF-HOOK mode for speakerphone operation according to the reception of the recipient's phone number (step S212). In the OFF-HOOK mode, the hook switch of the phone is switched to the off state, which means that the call is initiated by the IP phone, and an outgoing signal can be transmitted by inputting the recipient's phone number. It means that the mode is switched to the existing state.

After step S212, the IP phone transmits an outgoing signal to the recipient terminal corresponding to the recipient's phone number (step S214). As the state mode of the IP phone is switched to the OFF-HOOK mode, the IP phone may transmit an outgoing signal for a call to the recipient terminal corresponding to the recipient's phone number.

After step S214, a communication network connection is established for voice communication between the IP phone and the receiver terminal according to the transmission of the outgoing signal (step S216). As the network for voice communication between the IP phone and the receiver's terminal is connected, voice calls with the receiver's terminal are possible without the need to directly input a phone number stored in a smartphone or PC into the IP phone.
