Problems having friends join a party/lobby

Is anyone else still having these problems. I can join other parties/lobbies. But with one specific friend it won't let us join each other. Both or NATs are open. Weve both tried resetting our routers. I don't know what else to try

I have this problem every once in a while as well. i find that the mw3 join session in progress tends not to work so well. The only help I have for you would be to try inviting the person through the xbox menu, or to try and have them join your session in progress after the game is started.
