Remarks

Many TSPs provide functionality specific to the telephony system using device specific extensions. Four IDs in TapiDeviceSpecificExtensionID together specify a universally unique extension identifier that identifies a line device class extension. All 4 IDs are zeros if the line provides no extensions.

Please refer to the TAPI documentation for your telephony hardware to find out about device specific functionality supported by the telephony service provider.
