Thanks. You're right, it doesn't change anything. The client does not get any
responses to its requests after the successful REGISTER, and the incoming
NOTIFY responded with 405 Method Not Allowed (which shouldn't be the problem
because it isn't in other networks). I wonder if it should cause connection
errors to be reported by the stack, so that the user is aware of problems.

We should consider STUNning the binding, maybe as an option.
