To use this class you must call the lineNegotiateExtVersion API before opening the line. When lineNegotiateExtVersion is called ensure the highest bit is set on both the dwExtLowVersion and dwExtHighVersion parameters. This causes the call to lineOpen to behave differently. The line does not actually open, but waits for a lineDevSpecific call to complete the open with more information. The CCiscoLineDevSpecificUserControlRTPStream class provides the extra information that is required. CCiscoLineDevSpecific | +--CCiscoLineDevSpecificUserControlRTPStream Procedure 1. Call lineNegotiateExtVersion for the deviceID of the line that is to be opened (OR 0x80000000 with the dwExtLowVersion and dwExtHighVersion parameters). 2. Call lineOpen for the deviceID of the line that is to be opened. 3. Call lineDevSpecific with a CCiscoLineDevSpecificUserControlRTPStream message in the lpParams parameter.
