Did frazier and ali ever make peace?

Apart from Ali's apology coursed through Marvis Frazier in that locker room in Manila, he also asked for Joe Frazier's private number from the latter's publicist Butch Lewis. But Frazier wouldn't give his number. In the doentary "Beyond The Glory: Joe Frazier", it is mentioned that Ali and Frazier hugged and made up during an NBA All Star Game early in the decade. I don't know, however, if the gesture was sincere. I've always believed that Ali's taunts and insults on Joe were not personal and simply part of his shtick and psy-war tactics. After Ali's "near-death" experience in Manila, I thought his apology was sincere. Unfortunately, Joe's hatred for Ali had gone deep. I think it wasn't just Ali he's ranting about, but also what Frazier thought as his lack of recognition as a former heavyweight and Olympic champion.
