IP Phones - # Blocking

[olds]

Can end users block specific numbers calling in on a Cisco 7965?
My searches seem to indicate that it must be done by the system administrator.
I am trying to block a time share spammer that calls everyday. I know I can do it on my POTS phone and my cell phone.

TIA

Ya, I saw that article. That's what led me to belive one had to be some type of admin to do it. Was hoping I missed something.
