TSPI_phoneSetRing

  • Article

The TSPI_phoneSetRing function rings the specified open phone device using the specified ring mode and volume.

LONG TSPIAPI TSPI_phoneSetRing(
DRV_REQUESTID dwRequestID,  
HDRVPHONE hdPhone,          
DWORD dwRingMode,           
DWORD dwVolume );

Parameters

  • dwRequestID
    The identifier of the asynchronous request.
  • hdPhone
    The handle to the phone to be rung.
  • dwRingMode
    The ringing pattern with which to ring the phone. This parameter must be within the range from zero through the value of the dwNumRingModes member in the PHONECAPS structure. If dwNumRingModes is zero, the ring mode of the phone cannot be controlled; if dwNumRingModes is 1, a value of 0 for dwRingMode indicates that the phone should not be rung (silence), and other values from 1 through dwNumRingModes are valid ring modes for the phone device.
  • dwVolume
    The volume level with which the phone is to be rung. This is a number in the range from 0x00000000 (silence) through 0x0000FFFF (maximum volume). The actual granularity and quantization of volume settings in this range are service-provider specific. A value for dwVolume that is out of range is clamped by TAPI to the nearest value in range.

Return Values

Returns dwRequestID or an error number if an error occurs. The lResult actual parameter of the corresponding ASYNC_COMPLETION is zero if the function succeeds or it is an error number if an error occurs. Possible return values are as follows:

PHONEERR_INVALPHONEHANDLE, PHONEERR_RESOURCEUNAVAIL, PHONEERR_INVALPHONESTATE, PHONEERR_OPERATIONFAILED, PHONEERR_INVALRINGMODE, PHONEERR_OPERATIONUNAVAIL, PHONEERR_NOMEM.

Remarks

The service provider defines the actual audible ringing patterns corresponding to each of the phone's ring modes.
