Weird issue, only with registers. Sometimes when I start ser (and openser, same issue with both) my test phone (behind nat) will not register allways getting 401 unauthorized back. But wait a minute and it will register (without resetting ser or the phone).
Is this a built in feature or a bug (it only happens when I reset ser/openser after 60 seconds the server and phone behave normally).
Got me stumped as the configs on the phone and ser don't change.
