Had a question about call forwarding in GSM using USSD codes:

Some user has set up his/her gsm phone (with number A) to forward "all"
incoming calls to a certain number B using sequence *21*B# and some
caller C calls in A's number.

Is there any way we can obtain "original dialed number" (i.e. A) at
site B - before deciding to respond to the forwared call? At site B,
caller ID provides original caller (i.e. C) - but can we correctly
obtain "called id" by some means? Is it available at all?

Thanks.
