Narrative:

During descent we were given a clearance to depart ZZZ [VOR] on heading of 230 and descend to 8;000 feet. Concurrently another company aircraft; (flight abc) was given a descent clearance to cross 15 southwest of ZZZ [VOR] at 8;000 feet. They were subsequently given a frequency change. At ZZZ [VOR] we took up a 230 heading. At approximately 15 southwest of ZZZ [VOR] at 10;000 feet; the controller asked if we were going to comply with the 8;000 feet restriction 15 southwest of ZZZ [VOR]. I told him no; we were already at that point and we had not been given that clearance. The controller believed he had given us the same clearance as (company flight abc). He then gave me a frequency change and no further mention of the erroneous clearance.
