Hello,
if you set use_received param for path module, then the received address
in Route header is set as dst uri, see:
-
https://www.kamailio.org/docs/modules/stable/modules/path.html#path.p.enable_r2
All you need to do is:
loose_route();
t_relay();
Note that loose_route() is dealing with a pre-loaded Route header in
this case, see the readme of rr module for the return code.
Cheers,
Daniel
