[Serusers] routing question

[Vitaly Nikolaev]

That means that if I want that call in next step use RTP proxy I should
enable it in first step regardless if it needed or not ?

That is weird :)

Is there other way to to that ? 

I am trying to use rtp proxy only where it is absolutely necessary is
anybody accomplish this ?

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.
