I tried to call record_route_preset() in branch route in order to add
contact specific RR headers when request is forked to more than one

Duble attempt to record-route

Is it really so that record routing is not a branch specific thing?  Is
there a way to solve this problem?

I wonder what happens if you add a Record-Route header manually in the branch_route, with append_hf(), e.g.

   append_hf("Record-Route: <sip:ip.of.proxy:5060>\r\n");
