Responding to an OID_CO_TAPI_LINE_CAPS Query
In response to an OID_CO_TAPI_LINE_CAPS query, a call manager or MCM returns a CO_TAPI_LINE_CAPS structure that contains a LINE_DEV_CAPS structure. To support voice streaming, a call manager or MCM must specify the following values in the LINE_DEV_CAPS structure:
ulMediaModes
This field should contain LINEMEDIAMODE_AUTOMATEDVOICE, which maps to TAPIMEDIAMODE_AUDIO in TAPI 3.0.
ulAddressTypes
This field must be filled in appropriately. For a description of valid values, see the description of dwAddressTypes. This field must not be zero.
ulGenerateDigitModes
This field must be filled in with a bitwise OR of the LINEDIGITMODE_constants that specify the digit modes that can be generated on the line. For a description of the LINEDIGITMODE_constant, see the description of dwGenerateDigitModes.
ulMonitorDigitModes
This field must be filled in with a bitwise OR of the LINEDIGITMODE_constants that specify the digit modes than can be detected on this line. For a description of the LINEDIGITMODE_constants, see the description of dwMonitorDigitModes.
