The present invention relates to a three-way calling method using a wired telephone, and more particularly, by installing a cradle for mounting a mobile phone on a wired telephone, such as a mobile phone such as a PCS phone or a cellular phone. Wired and mobile phones that allow you to receive calls with the handset of your landline phone, and also allow you to make three-way calls between your landline phone and your mobile phone, while maintaining the convenience of charging your phone and minimizing the effects of electromagnetic waves without a separate charger. The present invention relates to a three-way intercom call and a landline telephone thereof.

In general, to make a call using a wired telephone, the wired telephone must be connected to a public telephone network (PSTN). Even if the receiver uses a mobile telephone such as a PCS phone or a cellular phone, the wired telephone itself is connected to the public network. It must be connected directly. Conversely, even if a caller uses a mobile phone to talk to a landline phone user, the receiver's landline phone must be directly connected to the public telephone network. This means that in order to make a call using a landline telephone, a public telephone network must be installed in the area where the landline telephone is used.
