Information processor, information processing method and non-transitory storage medium storing information processing program

An information processing method of controlling a device that receives a request for initiating a call between a phone on the calling side and a phone on the called side to perform call transmission with respect to the phone on the calling side and the phone on the called side, the information processing method comprising:

• registering a list of a plurality of IP address conversion servers performing IP address conversion needed for a call between the phone on the calling side and the phone on the called side;
• determining a location of the phone on the calling side or the phone on the called side;
• selecting the IP address conversion server to be used from the list, on the basis of the location of the phone on the calling side or the phone on the called side;
• executing, using the selected IP address conversion server, a call while performing IP address conversion for voice packets exchanged between the phone on the calling side and the phone on the called side;
• receiving a request for call initiation from a phone located outside a gateway;
• confirming an IP address of the phone;
• determining whether the phone is located outside the gateway;
• and
• requesting a call transmission by:
• requesting by data communication of a phone number of another party as a request parameter thereof using HTTP and FTP;
• calling to a representative number of a relay server to access the relay server, and then designating the other party using a push tone DTMF signal as an additional dial-in;
• and
• using an individual phone number that is allocated in advance to a user in the relay server.

A non-transitory computer-readable storage medium storing an information processing program comprising instructions for controlling a device comprising at least one processor to receive a request for initiating a call between a phone on the calling side and a phone on the called side to perform call transmission with respect to the phone on the calling side and the phone on the called side, the method comprising:

• registering a list of a plurality of IP address conversion servers performing IP address conversion needed for a call between the phone on the calling side and the phone on the called side;
• determining a location of the phone on the calling side or the phone on the called side;
• selecting the IP address conversion server to be used from the list, on the basis of the location of the phone on the calling side or the phone on the called side;
• executing, using the selected IP address conversion server, a call while performing IP address conversion for voice packets exchanged between the phone on the calling side and the phone on the called side;
• receiving a request for call initiation from a phone located outside a gateway;
• confirming an IP address of the phone;
• determining whether the phone is located outside the gateway;
• and
• requesting a call transmission by:
• requesting by data communication of a phone number of another party as a request parameter thereof using HTTP and FTP;
• calling to a representative number of a relay server to access the relay server, and then designating the other party using a push tone DTMF signal as an additional dial-in;
• and
• using an individual phone number that is allocated in advance to a user in the relay server.
