Parameters hCall A handle to the call on which tones are to be detected. The call state of hCall can be any state except idle. lpToneList A list of tones to be monitored, of type LINEMONITORTONE. Each tone in this list has an application-defined tag field that is used to identify individual tones in the list to report a tone detection. Calling this operation with either NULL for lpToneList or with another tone list cancels or changes tone monitoring in progress. dwNumEntries The number of entries in lpToneList. This parameter gets ignored if lpToneList is NULL. lineNegotiateAPIVersion The lineNegotiateAPIVersion function allows an application to negotiate an API version to use. The Cisco Unified TSP supports TAPI 2.0 and 2.1. Function Details LONG lineNegotiateAPIVersion( HLINEAPP hLineApp, DWORD dwDeviceID, DWORD dwAPILowVersion, DWORD dwAPIHighVersion, LPDWORD lpdwAPIVersion, LPLINEEXTENSIONID lpExtensionID ); Parameters hLineApp The handle by which the application is registered with TAPI. dwDeviceID The line device to be queried. dwAPILowVersion The least recent API version with which the application is compliant. The high-order word specifies the major version number; the low-order word specifies the minor version number. dwAPIHighVersion The most recent API version with which the application is compliant. The high-order word specifies the major version number; the low-order word specifies the minor version number. lpdwAPIVersion A pointer to a DWORD-sized location that contains the API version number that was negotiated. If negotiation succeeds, this number falls in the range between dwAPILowVersion and dwAPIHighVersion.
