Hi Leonard, The '481 Subscription does not exist' reply is only for Subscriptions inside a dialog for which the presence server has no record. It might be because you emptied the database and lost stored dialogs and a client remained running. Most of the clients after receiving a 481 reply, delete the old dialog and start a new one by sending an initial Subscribe request. So that eventually the subscription i s successful. The best way to test, however, is to close down all your clients and then, after turning them on again you should see no 481 reply. Regards, Anca Vamanu Leonard Broman wrote:
