Well, anyone with a buttset can camp onto POTS lines and draw dialtone or monitor a call in progress.

With a T1 it would be harder in that you would need to be able to demux a full 24 channels for non-ISDN/PRI service or 23 for ISDN/PRI. Such activity requires specialized equipment and is most easily done back in the C.O.
