Narrative:

While cruising at FL270, center gave us a crossing, cofax intersection at FL250. Captain inserted FL250 in the MCP while I confirmed according to our altitude awareness program. The FMC was already programmed for the crossing and the autoplt in LNAV and VNAV. Then center gave us a new speed, and the captain chose manual, taking the autoplt out of VNAV and monitored the descent page in the FMC. Prior to the top of descent, a call from the flight attendant was received. While a discussion of their request was taking place, we passed the top of descent. Center called and asked if he had given us a crossing level FL250 at cofax. We had already began a maximum descent and crossed cofax 850 ft high. We inquired as to any conflict and advised level FL250. He replied no conflict and gave us a frequency change.
