Yes, your telco will need to configure your PRI as NI-2 signaling, and 
you will need to wait at least one second on incoming calls before doing 
anything that requires the Calling Name information (it is not delivered 
in the initial Call Setup packet, it is delivered in an additional 
packet later in the call).
