Just to understand exactly:
A calls B B redirects to C and is captured by proxy
then from proxy you have two parallel outgoing branches to C?
How you take the address of C and create the branch? uac_redirect or other script functions?
Yes, your understanding of the scenario is correct.
No, I do not use any of the uac_* or contacts functions. I manually catch the 302 in a failure_route, manually parse out the relevant details from the Contact header, rewrite the RURI (prior to append_branch()), append_branch() and t_relay().
append_branch() is not needed anymore (for couple of releases, actually, being added in one of the 3.x releases), but should be harmless unless you do other changes of r-uri/dst-uri after append_branch(). Can you try without append branch?
Also, can you look at config execution trace to be sure append branch is not called twice somehow?
