Daniel,
First and foremost, thank you very much for implementing this. I have been buried with work lately, and resultingly have not had the opportunity to chime in on this thread or to thank you for such a prompt response to this desire.
I would concur with Juha that for the use-cases I've got in mind[1], the completion of the init route prior to processing SIP messages is highly desirable.
