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 contact. What happened was that I got error message:
Sep 26 17:03:47 wheezy2 /usr/sbin/sip-proxy[2436]: ERROR: rr [rr_mod.c:256]: 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 "solved" it by not using record_route_preset() at all. instead i used append_hf, which seemed to do the same thing on per branch basis. i wonder if there is any point in having record_route_preset() function?
I think it integrates better with the rest of the rr functions, like adding rr params set by dedicated config function.
The error comes from a safety check based on internal flag to avoid calling many times record routing in request_route, but probably it can be relaxed for branch_route.
