Description

technical field [0001] The invention relates to an internet phone for sending / receiving voice through the Internet and a general phone for sending / receiving voice using a public switched telephone network, in particular to a system and method for using a mobile communication terminal for using a network phone and a general phone. Background technique [0002] Generally speaking, if figure 1 As shown, compared with the general telephone in the PSTN-Public Switched Telephone Network (PSTN-Public Switched Telephone Network), which pays different fees according to different distances, the Internet telephone does not need to pay the fee in the Internet interval, and only needs to pay the receiving telephone exchange to the receiving telephone office.

AI Technical Summary

Problems solved by technology

[0004] Ordinary telephones, using telephones installed in the public switched telephone network, can only enable linked users who are relatively close to use multiple telephones through one telephone line, but cannot use them in other spaces

[0005] In addition, the Internet phone or Internet phone terminal is connected to the network cable through a wired method, or can only be used within a certain radius of the AP (Access Point) device, where the wireless network can be used, so it is restricted by space

[0006] Therefore, even if the Internet phone or ordinary phone is connected to the network, if it is not in the same space as the Internet phone terminal and the general phone, only mobile communication terminals such as mobile phones or other wired phones can be used, which requires additional costs

[0007] Moreover, in a company or group where multiple members share Internet phones and ordinary phones, if members who are often on the go or on business trips call a partner manufacturer or a member of the manufacturer, they can only use a phone that is not the phone number of the company representative.
