1. A method for controlling an IP phone used between a computer and a proximal IP phone, the computer and the proximal IP phone being connected to the same local area network, wherein an application program is installed and executed at the computer, the control method comprising:

  • a) establishing connection between the computer and the proximal IP phone;

    b) providing a graphical user interface (GUI) web page by the application program to offer a plurality of virtual keys respectively corresponding to hardware functions of the proximal IP phone on the computer, wherein the plurality of virtual keys comprising a plurality of virtual BLF (Busy Lamp Field, BLF) keys, a plurality of virtual operation keys and a plurality of virtual expansion keys, the plurality of virtual BLF keys corresponding to BLF key functions of the proximal IP phone, the plurality of virtual operation keys corresponding to operation key functions of the proximal IP phone, and the plurality of virtual expansion key corresponding to undefined functions of the proximal IP phone, wherein the quantity of the plurality of the virtual BLF keys is larger than the quantity of the physical BLF keys of the proximal IP phone, so that when the computer controls the proximal IP phone, the application program is used for expanding hardware functions of the proximal IP phone;

    if the proximal IP phone is a low cost device having basic functions and does not have enough BLF keys, or does not have BLF keys to cause inconvenient in field application, the plurality of virtual BLF keys simulates the function as additional BLF keys and adds additional virtual BLF keys to the proximal IP phone;

    if an operation panel of the proximal IP phone is too simple to meet subscriber demands and does not have enough operation keys, the function performed by the proximal IP phone is accordingly limited and is inconvenient to subscribers, the function of the proximal IP phone cannot be performed at the same time, or subscribers have to purchase additional hardware devices for using functions of the undefined operation keys, the plurality of virtual expansion keys are associated with corresponding undefined function and save additional hardware cost for subscribers via setting up at the GUI web page;

    c) using the GUI web page for transferring data between the computer and the proximal IP phone;

    d) sending first control command to the proximal IP phone according to the data;

    e) establishing connection by the proximal IP phone with remote phone according to the first control command; and

    f) establishing connection by the computer with the remote phone via the proximal IP phone.
