That's generally what I always do - manual routing for in-dialog requests.

I was not aware that loose_route() is required for correct routing of
in-dialog requests when they are record-routed back through the proxy.

I think one of the reasons why this may not be much of an issue for me
is because my proxy applications generally always have the proxy as the
URI domain - I won't relay for !uri == myself.  So, after the initial
INVITE is rewritten, the UAC/UAS cores on either side send subsequent
in-dialog requests to the same URI they sent the INVITE to.

I would, of course, be eager to hear any methodological insights you may
offer about what I'm doing incorrectly.
