I think you need to check your settings and the settings Carrier's, this sip message most likely about the Carrier is not waiting for messages from you from your IP. After 407, if everything is fine, the Carrier should send REGISTERED as a result.

If you share you router configuration, minus any sensitive info we might be able to help you. Please put it in a text file and attached that to your answer.
