Script to auth. users and control the remote phone number used

[Luis]

Hi, the problem is that I want to control the access not only based in
the username and the password but also using the   remote telephone
number used by the user to do the call.

So, if the phone number is from Spain it doesn´t matter if the username
and the password are correct, radius should reject the access.

Is that possible using freeradius?
I don´t know exactly if Called-Station-Id can be used (and how) to do
that type of control.

Regards.
