First, make your proxy work without messing with headers. After that
incrementally add changes.
so I turned on the called_matching parameter and
turned off
ruri_matching and via1_matching. I get the same result as before making
that change of the t_check_trans() not returning a positive value.

This part of the script has nothing to do with matching the replies to the

This is a messed-up Via header. The request is also missing the Via header
from the previous hop (Freeswitch).
