I am using Mid-Registrar and Dispatcher to load balance to the SBCs. I am able to get Registrations and Calls working, but the issue I am having is with the Subscribe messages not receiving the NOTIFY response. Since it is set as a stateful proxy the out of dialog messages are coming directly to the users public IP. So Notify is being dropped at the firewall as its not coming from the same IP address that the phone is registered to. <div><br></div><div>Is there a mechanism to remedy this other than full B2BUA? </div><div>If B2BUA is the only path, what is the best way to set this up?<br></div><div><br></div><div>Thank you.</div><div><br></div></div>
