Abstract:
A communication terminal includes a display control unit configured to display, on a display unit, a function selecting screen that contains a first icon for receiving a selection of a first communication function and a second icon for receiving a selection of a second communication function. The first communication function is to provide communication using a signaling protocol for connecting to or disconnecting from a destination of communication and an encoding protocol for encapsulating communication data in IP packets. The second communication function is to provide communication using the same signaling protocol and a different encoding protocol. The communication terminal also includes a receiving unit configured to receive a selection of the first icon or the second icon; and a starting unit configured to start the first communication function and the second communication function in response to the selection of the first icon and the second icon, respectively.
Abstract:
A processor associates with one another terminal identifiers for identifying terminals. Each terminal identifier includes a to-be-authenticated section common to the terminal identifiers and used to authenticate a user. The processor associates the terminal identifiers with one another as respective terminal identifiers for a communication source and a communication destination that can perform communication with the communication source. Upon receiving from a first terminal as a communication source a first terminal identifier for identifying the first terminal and a second terminal identifier for identifying a second terminal as a communication destination, the processor transmits a request to the second terminal to start communication with the first terminal for a case where the first and second terminal identifiers are associated with one another. Otherwise the processor does not transmit a request to the second terminal to start communication with the first terminal.
