<p>A net phone that is not only used to make an net call, but also switched as home phone or cellular phone system in order to call another person. This allows the user to select the desired phone appropriately to call another person, which makes the expenditure of the call reduced or free. If no one answers the call made from another net phone to the present net phone, the call can be transferred to the mobile phone system on the net phone, which activates the inner control-transfer circuit so that the call from the another net phone is transferred to the mobile phone of the called person via the mobile phone system on the said net phone. The mobile phone system of the said net phone and the mobile phone system of the called person are of the same telecom system, thereby providing a net call within the same system to reduce the cost without missing any net call.</p> |
