Narrative:
In cruise flight at FL220; erroneously read back an altitude clearance to FL230 for an other aircraft. Climbing through FL218 ATC advised us that we had taken another flight's clearance. He then cleared us to maintain FL220. Although ATC had flight abcc and aacc under his control both aircraft were on a different frequency. On read back; ATC also did not advise us that he was talking to a similar call sign.
