Method and apparatus for supporting call control of circuit domain telephone and VoIP |
摘要 |
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. |

1. An apparatus for supporting call control for both circuit domain telephone and Voice over Internet Protocol (VoIP), the apparatus comprising:
an off/on-hook detection module, configured to send detected off-hook events; a circuit domain telephone call control module, configured to receive off-hook events and all events during the call associated with the off-hook events from a call flow control module, and process incoming/outgoing call events of the circuit domain telephone; a VoIP call control module, configured to receive off-hook events and all events during the call associated with the off-hook events from a call flow control module, and process incoming/outgoing call events of the VoIP; the call flow control module, configured to receive off-hook events from the off/on-hook detection module, save the received off-hook events and judge whether a user makes a circuit domain telephone incoming/outgoing call or a VoIP incoming/outgoing call according to the number dialed by the user; when the incoming/outgoing call is the VoIP call, to send the received off-hook events and all events during the call associated with the off-hook events to the VoIP call control module; when the incoming/outgoing call is the circuit domain telephone call, to send the received off-hook event and all events during the call associated with the off-hook events to the circuit domain telephone call control module; wherein, the off/on-hook detection module is further configured to send a timer event; and the call flow control module is further configured to regularly detect whether a Session Initiation Protocol (SIP) signaling with a non-null network session domain is received according to the timer event from the off/on-hook detection module, and to determine that the VoIP incoming call is received when the SIP signaling with the non-null network session domain is received. |
