Narrative:

Several mi east of pensacola airport heading 180 degrees descending to 1700 ft with expectation of clearance to visual approach upon breaking out of WX at 2000 ft. We called 'airport in sight' to approach control and believe we heard 'cleared for visual approach to runway 35 contact tower'. Upon contacting tower, we were told we weren't cleared for the visual approach. We apologized and went back to approach control. Approach control did not respond to our call so we went back to tower. Tower cleared us to land. There were no conflicts, no aircraft in area or on final as I recall. This was our third flight segment of the day and about 5 hours into our duty day. I believe this situation was the result of a missed communication/misunderstanding during a busy critical phase of flight.
