I can tell you about the situation here in Greece, and can't tell that 
properly either since I don't have a thorough understanding of several 
telephony issues: What's done is that the B-Channel is opened while the 
call is still in progress, signalling-wise. Then a short message is 
delivered, the channel is closed and the call rejected with an 
appropriate cause value.
