ITBasicCallControl::Dial method (tapi3if.h)
The Dial method dials the specified address.
Syntax
HRESULT Dial(
[in] BSTR pDestAddress
);
Parameters
[in] pDestAddress
Pointer to BSTR representation of address to be dialed. The format must conform to a standard dialable address.
Return value
This method can return one of these values.
| Value | Meaning |
|---|---|
|
Method succeeded. |
|
Insufficient memory exists to perform the operation. |
|
The pDestAddress parameter is not a valid pointer. |
|
The operation failed because the TAPI 3 DLL timed it out. The timeout interval is two minutes. |
Remarks
The application must use SysAllocString to allocate memory for the pDestAddress parameter and use SysFreeString to free the memory when the variable is no longer needed.
In some cases, the application may need to use the address translation interfaces ( ITAddressTranslation and ITAddressTranslationInfo) to obtain a pDestAddress string in the proper format.
The Dial method differs from ITAddress::CreateCall in that the call already exists. An example use is dialing an extension.
