DEPARTURE: OE-DMS, roger. Continue direct Munich. Next frequency Innsbruck Centre on one-three-two decimal zero. Report changing frequency.

PILOT: ROGER, direct Munich, Innsbruck Centre one-three-two decimal zero, report changing frequency, OE-DMS.

Analysis: ATC acknowledged your level-off report and gave you a new routing (direct Munich) and a frequency change to Innsbruck Centre. You read back the frequency change requirement ("report changing frequency"), which is a new procedure word: you must inform ATC when you switch frequencies. This prevents gaps in coverage where neither station can hear you.
