2.2.4.1.3.53 RemoveFromConference
The RemoveFromConference packet is transmitted from a TAPI client to a TAPI server in a remote procedure call. Sending this packet removes the specified call from the conference call to which it currently belongs. The remaining calls in the conference call are unaffected.

Req_Func (4 bytes): An unsigned 32-bit integer. Identifier of the function that will be invoked on the remote server. This value MUST be set to 63.

Return Values
-
On completion of ClientRequest, this field will contain the result of the encapsulated telephony request. A nonzero request ID value indicates that the request is in progress and will complete asynchronously, and a LINEERR_Constants value indicates synchronous failure.
-
Returns a positive request identifier if the function will be completed asynchronously or a negative error number if an error occurs. The dwParam2 parameter of the corresponding LINE_REPLY packet is zero if the function succeeds, or it is a negative error number if an error occurs. If the client specified a nonzero value in the dwRequestID field of the packet, the same MUST be used as the value for the returned positive request identifier. Common return values are as follows:
-

Reserved1 (4 bytes): An unsigned 32-bit integer. MUST be set to zero when sent and MUST be ignored on receipt.
dwRequestID (4 bytes): An unsigned 32-bit integer. The identifier of the asynchronous request.
hCall (4 bytes): A HCALL. Handle to the call to be removed from the conference. The application MUST be an owner of this call. The call state of hCall must be conferenced. The client must have sent the AddToConference packet to have hCall in the conference state.
