Totalsize (4 bytes): An unsigned 32-bit integer. The total size, in bytes, of this packet and any trailing variable-length data.

InitContext (4 bytes): An unsigned 32-bit integer. An opaque, client-specified session value that MUST be equal to the InitContext value specified in the original scoping of the phone Initialize request.

lpContext (4 bytes): An unsigned 32-bit integer. An opaque, client-specified value that MUST be equal to the lpContext value in the original request.

hDevice (4 bytes): An unsigned 32-bit integer. This MUST be ignored on receipt and can be any value.

Msg (4 bytes): An unsigned 32-bit integer. The packet type identifier. MUST be set to PHONE_REPLY (0x00000011).

OpenContext (4 bytes): An unsigned 32-bit integer. An opaque, client-specified value that MUST be equal to the OpenContext value specified in the original scoping of the phone Open request.

dwRequestId (4 bytes): An unsigned 32-bit integer. The positive, nonzero, client-specified request ID value equal to the dwRequestID value in the original request.

Result (4 bytes): An unsigned 32-bit integer. The request result, for example, 0 for success or a LINEERR_Constants value for an error.

lpParamsContext (4 bytes): An unsigned 32-bit integer. An opaque, client-specified value that MUST be equal to the lpParamsContext value in the original phone DevSpecific request.

dwSize (4 bytes): An unsigned 32-bit integer. The size, in bytes, of any returned variable-length data that is returned in VarData field.

VarData (variable): Opaque data sent to the client according to the corresponding original DevSpecific request. The server provides padding to ensure that the entire packet is aligned on a QWORD boundary, as specified in [MS-DTYP] section 2.2.40.
