BO2 multiplayer with friends question

[JesterAA16]

me and my friend want to play regular mp servers (not custom match) together, we can join each others session just fine but if the host connects to a server through "server browser" the host can join but
the other player doesn't join and a message display saying "party is no longer available" or something
and if one of us tries to join session in progress while the other is in a game he also gets kicked out with a error saying "unable to join session"

so can we join together or is it not possible okay thanks.

JesterAA16 parties don't work on dedicated servers, ofc you can join the same server your friend plays on but you won't be in a party anymore.
