[OpenSIPS-Users] 302 redirect question

[Brett Nemeroff]

Bogdan / Jeff,
Thanks for the replies. I got it working now with serialize_branches.
Just goes to show that sometimes the magic is "up to you". :)

Question tho. I know serialize_branches order branches by q-value.
However, does it smartly handle q-values that are the same to be
parallel branches? Unfortunately I don't have a simple way to test
that out.

Thanks,
Brett
