Abstract:
1. A communication device configured to be connected with both a public switched telephone network and an IP network, the communication device comprising: a memory configured to store at least one provider information and a predetermined domain name, the at least one provider information indicating at least one provider that is capable of providing the communication device with a state that is capable of executing a first communication process, the predetermined domain name indicating the at least one provider; and a processor configured to cause the communication device to perform: acquiring, from a server connected with the communication device, provider related information being related to a provider that a user enters into a contract with; judging that the communication device itself is in a specific state that is capable of executing the first communication process of communicating via the IP network using IP identification information for the IP network, in a case where the acquired provider related information is identical with any one of the at least one provider information stored in the memory, the IP identification information including identification information for the public switched telephone network; judging that the communication device itself is not in the specific state, in a case where the acquired provider related information is not identical with any one of the at least one provider information stored in the memory; allowing the user to select an operating mode of the communication device, allowing the user to input first identification information for the public switched telephone network; generating first IP identification information including the first identification information and the predetermined domain name by combining the first identification information input by the user and the domain name; executing the first communication process using the generated first IP identification information, in a first case where the communication device itself is judged as being in the specific state, the first identification information is input by the user, and a first operating mode for communication via the public switched telephone network is selected; executing a second communication process of communicating via the public switched telephone network using the first identification information, in a second case where the communication device itself is judged as not being in the specific state, the first identification information is input by the user, and the first operating mode is selected; allowing the user to input second identification information for the public switched telephone network, the second identification information being different from the first identification information; generating second IP identification information including the second identification information and the predetermined domain name by combining the second identification information input by the user and the predetermined domain name; executing the first communication process using the generated second IP identification information, in a third case where the communication device itself is judged as being in the specific state, the second identification information is input by the user, and the first operating mode is selected; executing the second communication process using the second identification information, in a fourth case where the communication device itself is judged as not being in the specific state, the second identification information is input by the user, and the first operating mode is selected; allowing the user to input third IP identification information for the IP network; and executing the first communication process using the third IP identification information, in a case where a second operating mode for communicating via the IP network is selected, and the third IP identification information is input by the user.
