Narrative:
On bvt 2 arrival into mdw, ZAU (135.75) gave us a crossing restr to cross 40 mi south of cgt at 11000 ft MSL. We made the restr, but head no further calls for us for quite sometime. Approaching cgt, still at 11000 ft MSL, we realized we were going to be high, and discussed that ATC must have forgotten about us. We asked if they had a heading for us. Their reply was to go to another center frequency, followed immediately by another voice telling us to go to chicago approach on 118.4, and expect an immediate descent. Approach informed us that we had gotten into ord arrival airspace, and to descend to 2500 ft MSL. He said center said we were 'lost on frequency.' after vectors to get us down, the approach and landing were normal. From their comments, both controllers made it sound like we missed a frequency change, and this was our fault. However, on the way in we had no distractions, and were both listening to the radio the whole time except for a brief call to operations to get a gate. Neither of us heard a call for us, and we think the controllers at center just forgot about us. In retrospect, I wish I'd asked the controllers for lower a bit earlier. I started trying around 10 NM out of cgt, but due to congestion on frequency, couldn't get through until almost over cgt, which made us very high.

Title: A B737-200 FO RPTED THAT, AFTER BEING HANDED OFF FROM 1 CTLR TO THE NEXT THAT C90 SAID THEY HAD BEEN DECLARED 'LOST ON FREQ' BY ZAU.
Narrative: ON BVT 2 ARR INTO MDW, ZAU (135.75) GAVE US A XING RESTR TO CROSS 40 MI S OF CGT AT 11000 FT MSL. WE MADE THE RESTR, BUT HEAD NO FURTHER CALLS FOR US FOR QUITE SOMETIME. APCHING CGT, STILL AT 11000 FT MSL, WE REALIZED WE WERE GOING TO BE HIGH, AND DISCUSSED THAT ATC MUST HAVE FORGOTTEN ABOUT US. WE ASKED IF THEY HAD A HEADING FOR US. THEIR REPLY WAS TO GO TO ANOTHER CTR FREQ, FOLLOWED IMMEDIATELY BY ANOTHER VOICE TELLING US TO GO TO CHICAGO APCH ON 118.4, AND EXPECT AN IMMEDIATE DSCNT. APCH INFORMED US THAT WE HAD GOTTEN INTO ORD ARR AIRSPACE, AND TO DSND TO 2500 FT MSL. HE SAID CTR SAID WE WERE 'LOST ON FREQ.' AFTER VECTORS TO GET US DOWN, THE APCH AND LNDG WERE NORMAL. FROM THEIR COMMENTS, BOTH CTLRS MADE IT SOUND LIKE WE MISSED A FREQ CHANGE, AND THIS WAS OUR FAULT. HOWEVER, ON THE WAY IN WE HAD NO DISTRACTIONS, AND WERE BOTH LISTENING TO THE RADIO THE WHOLE TIME EXCEPT FOR A BRIEF CALL TO OPS TO GET A GATE. NEITHER OF US HEARD A CALL FOR US, AND WE THINK THE CTLRS AT CTR JUST FORGOT ABOUT US. IN RETROSPECT, I WISH I'D ASKED THE CTLRS FOR LOWER A BIT EARLIER. I STARTED TRYING AROUND 10 NM OUT OF CGT, BUT DUE TO CONGESTION ON FREQ, COULDN'T GET THROUGH UNTIL ALMOST OVER CGT, WHICH MADE US VERY HIGH.
