PHONEEXTENSIONID structure (tapi.h)
The PHONEEXTENSIONID structure describes an extension identifier. Extension identifiers are used to identify service provider-specific extensions for phone device classes. The phoneNegotiateAPIVersion and TSPI_phoneGetExtensionID functions return this structure.
Syntax
typedef struct phoneextensionid_tag {
DWORD dwExtensionID0;
DWORD dwExtensionID1;
DWORD dwExtensionID2;
DWORD dwExtensionID3;
} PHONEEXTENSIONID, *LPPHONEEXTENSIONID;
Members
dwExtensionID0
First part of the extension identifier.
dwExtensionID1
Second part of the extension identifier.
dwExtensionID2
Third part of the extension identifier.
dwExtensionID3
Fourth part of the extension identifier.
Remarks
These four members together specify a universally unique extension identifier that identifies a phone device class extension. This structure may not be extended.
Extension identifiers are generated using an SDK-provided generation utility.
