IVoIPMgr::Initialize

  • 项目

This method initializes the VoIP manager. Initialization includes provisioning of the phone, attempts to register with the SIP server, and creation of subsequent data structures (databases, etc). This method must be called before any other manager methods. Otherwise, all methods related to setting parameters and receiving and making calls will fail with a VOIP_E_NONINITIALIZED return value.

HRESULT Initialize( 
  IVoIPUI* piUI, 
  VoIPMgrParameters* pvmpMgrParams 
);

Parameters

  • piUI
    [in] Pointer to the IVoIPUI interface to receive asynchronous callback events from the VoIP manager.
  • pvmpMgrParams
    [in] Pointer to a VoIPMgrParameters structure that contains the parameters necessary to initialize the directory client and register with the SIP server. Some or all structure fields are filled in. The VoIP manager will fill the rest of the structure with defaults.
