incoming calls restriction on 7610

I'm wondering, if someone knows...
On few of my old, old phones like Siemens S35 and some Ericssons (R320, t39... ) I had this option, to simply allow only certain groups or numbers to get me, for all the rest I could be unavailable or busy. I've been going through the meny and user book and I couldn't find that on 7610. Yes, there is "incoming calls barring" in meny but it's an option/service provided by network and not by phone itself, besides it then restricts all calls.
I really need to get rid of few man, and this would do the job, I just hope I won't be needing go back to Ericsson t39 for this.
If someone has a solution to this problem... PLEASE!!
