A method and apparatus for supporting call control of circuit domain telephone and Voice over IP (VoIP) are provided by the present invention, and the apparatus includes a call flow control module, which is for receiving and storing off-hook events and judging if the user makes a circuit domain telephone call or VoIP call according to the number dialed by the user; if making a VoIP call, sending the off-hook event to a VOIP call control module, and sending all the events in the present call to the VoIP call control module for processing; if making a circuit domain telephone call, sending the off-hook event to a circuit domain telephone call control module, and sending all the events in the present call to the circuit domain telephone call control module for processing. By the call control apparatus and the implemention method thereof in the present invention, the compatibility between the circuit domain telephone and the VoIP is realized by using a single Foreign Exchange Station (FXS), and since the circuit domain telephone and VoIP can share one Subscriber Line Interface Circuit (SLIC) chip, one SLIC chip is saved and the cost is saved dramatically. |
