lineSetCallTreatment
The lineSetCallTreatment function sets what sounds a party on a call that is unanswered or on hold
will hear. Except for basic parameter validation, it is a straight pass-through by
TAPI to the service provider.
LONG lineSetCallTreatment(
HCALL hCall,
|
| DWORD dwCallTreatment
|
| );
|
|
Parameters
hCall
Handle to the call. The application must have OWNER privilege.
dwCallTreatment
One of the call treatments supported on the address on which the call appears,
as indicated by LINEADDRESSCAPS. LINEERR_INVALPARAM is returned if the specified treatment is not supported.
Return Values
Returns a positive request identifier if the asynchronous operation starts;
otherwise, one of these negative error values:
LINEERR_INVALCALLHANDLE, LINEERR_INVALCALLSTATE, LINEERR_INVALPARAM,
LINEERR_NOMEM, LINEERR_NOTOWNER, LINEERR_OPERATIONFAILED, LINEERR_OPERATIONUNAVAIL,
LINEERR_RESOURCEUNAVAIL, LINEERR_UNINITIALIZED.
Remarks
The use of call treatment functionality should be limited to controlling of
legacy equipment. New equipment is generally designed so that instead of call
treatments being generated by external switching equipment, calls would be
connected to PC-based audio sources and signals generating using standard Win32
functions such as the multimedia Wave API.

Nostalgia .Net |

.Net is powerful, but not all-powerful, so sometimes we need to use Win32 API for our .Net applications. It's simple enough with Platform Invoke if you have Win32 skill, but we do not always have time to dig the ancient documentation, declare the special types that are compatible with Win32, find the values of the Win32's constants and so on. Nostalgia .Net offers several simple-to-use classes, and components that will allow you to forget about the headache of Win32 and just use the power of Win32 in your application the same way as you use the native. Net classes. More » |
