Andy,
The point is there aren't any credentials.
Anyway, thanks for the ideas.

a.
I do not know why reply_route seems to call the
main route block again. I do know that if I comment out
the authentication code in the main route block my forwarding
works. If I do not comment it out, then the forwarding
fails with an 'Unauthorized' directed at the pstn gateway.
Presumably, you rewrite the URI with a URI which results in
a loop over loopback interface. That causes a request to be
forwarded to the server again as a new transaction, which is
subject to authentication checks again. You can verify it by looking
at via_cnt in Warning header field of replies or by watching
local interface. There are different ways of dealing with it
-- not challenging request coming from itself, forwarding to
gateway directly (as opposed through itself), for example.
