The RADIUS accounting and authentication packets for ISDN connections include
the Calling-Station-Id (Caller-ID), and also the Called-Station-Id, which
gives the number the user dialed.

I know this is available on PRI, but is it also provided with Channelized T1
service? I'm specifically interested in Ameritech's service.
