Password for IVR - filtering VIP callers

Hi, what are the possibilities to filter incomming calls to IVR or directly to a line? I.e. you have VIP customers with paid support, they have security PIN to go through IVR to a right person. 

There is manual, it is rather old. Is it still possible with actual HW PBX series? 


And how about Cloud PBX, any chance to do something like this? Thanks
