As Daniel already replied you, SIP replies are handled in reply routes<br>
based on Via.<br>
You are posting a request route snippet which doesn't handle at all replies.<br>
Please do what has been asked to you, write on the users mailing list and<br>
there people will tell you if it is a bug or not.<br>
