Hello,
if you need this desperately, here is a quick and dirty solution: program a CTI route point, add a line where the DN equals to your phone number (of course, must be in a different partition), forward all calls from this CTI route point to your real phone number with a CSS in which there is only one partition, containing your phone line). In Plain English, you will have a setup where all calls to your phone number will hit that CTI route point (which is, of course, forwarded to your phone). Nothing is seen on your phone.
Of course, CTI Route point is just another device, if you assign it to a user, you can even manage it using the CCMUser interface.
I know it is not a perfect solution, but here we go...
