IVoIPMgr2::InitializeEx (Windows CE 5.0)
This method initializes the VoIP Manager. Initialization includes provisioning of the phone, registration with the SIP server, and creation of data structures like call log databases.
This method must be called before any other IVoIPMgr methods. If this method is not called, all methods related to setting parameters and receiving and making calls will fail with a VOIP_E_NOTINITIALIZED return value.
This method replaces the IVoIPMgr::Initialize method, which is no longer supported.
HRESULT InitializeEx(
IVoIPUI *piUI);
Parameters
- piUI
[in] Pointer to the IVoIPUI implementation that will receive asynchronous callback events from the VoIP Manager.
Return Values
If RTC cannot be loaded or initialized, this method will return an RTC_E_constant.
The following table shows additional possible return values.
| Value | Description |
|---|---|
| E_OUTOFMEMORY | There was not enough memory to create VoIP data structures. |
| E_POINTER | The piUI pointer is NULL. |
| S_OK | The VoIP manager was initialized correctly. |
| VOIP_E_ALREADYINITIALIZED | The VoIP manager is already initialized. |
