[Serusers] routing question

[Jan Janak]

failure_route works with the original request (not response). SER will
trigger failure_route when it decides what response code (from which
branch) should be forwarded upstream. It is not possible to call
force_rtp_proxy in this section, you should call force_rtp_proxy in the
main routing section.
