Narrative:
During pushback everything went normally; initially. We received 'clear to start engines' over headset and started engines. The aircraft came to a complete stop and no command was given that the push was complete or to set parking brake. I made several attempts to determine status of pushback on headset with no reply. After a couple of minutes; headset communications were re-established with the tug driver and he asked 'is parking brake set' and I replied 'no; do you want the parking brake set?' he replied 'set parking brake' and I set parking brake and replied 'parking brake set'. We heard a lot of banging sounds and I asked if they had a problem with the tow bar and the reply was that the tow bar was wedged between the nose gear wheels. Aircraft maintenance came out to inspect and we discussed options over the headset to remove tow bar. Talked to flight attendants; passengers; ground control; ramp control; directly. Free text messaged dispatch and later directly on remote frequency and later by cell phone during the time after problem occurred. We had made arrangements for unloading passengers by stairs and busing passengers to terminal when maintenance was successful in removing tow bar from nose gear and noted that the nose gear appeared to be undamaged. With another tow bar; were towed back to our original gate.
