Narrative:
ZOB issued clearance to us 60 mi south of djb at FL260. Read back clearance using air carrier altitude awareness procedures. A little while later we had a frequency change. We checked in to ZOB, air carrier X FL310. ZOB asked if we had a crossing restr, we said yes, 60 mi south of djb at FL260. We started our descent and around FL269 ZOB asked our altitude. We replied, just about to level FL260. ATC said that was fine, but we were only cleared to FL280. We told center we read back the clearance 60 mi south djb FL260 when we checked in with him. He said not a problem just maintain FL260.

Title: B737-200 FLC DSNDS TO FL260 AS FINAL FOR ALT XING RESTR. THERE HAD BEEN A FREQ CHANGE PRIOR TO DSCNT. NEW CTLR DISPUTES THEIR CLRNC AS BEING FL280. CREW HAD GIVEN NEW CTLR THE ALT RESTR OF FL260 PRIOR TO LEAVING FL310.
Narrative: ZOB ISSUED CLRNC TO US 60 MI S OF DJB AT FL260. READ BACK CLRNC USING ACR ALT AWARENESS PROCS. A LITTLE WHILE LATER WE HAD A FREQ CHANGE. WE CHKED IN TO ZOB, ACR X FL310. ZOB ASKED IF WE HAD A XING RESTR, WE SAID YES, 60 MI S OF DJB AT FL260. WE STARTED OUR DSCNT AND AROUND FL269 ZOB ASKED OUR ALT. WE REPLIED, JUST ABOUT TO LEVEL FL260. ATC SAID THAT WAS FINE, BUT WE WERE ONLY CLRED TO FL280. WE TOLD CTR WE READ BACK THE CLRNC 60 MI S DJB FL260 WHEN WE CHKED IN WITH HIM. HE SAID NOT A PROB JUST MAINTAIN FL260.
