[OpenSIPS-Users] Branch Flags

[Răzvan Crainea]

Hi, Ben!

Unfortunately the `setbflag` function only accepts static indexes, 
that's why it doesn't work no matter how you try.
Perhaps the only scenario where a static branch is useful is when you 
"manually" add branches in your script (using append_branch), and you 
know exactly the order those branches were added, and how to index them.

I believe I ran into this issue a while ago, and I was able to solve it 
by using an AVP, and indexing it using the branch index. I know it's not 
the best way to do it, but it worked for me back then :)
