[OpenSIPS-Users] Branch Flags

[Ben Newlin]

Razvan,

Thanks for the quick response. I'm testing a workaround using the $bavp variable type exported by the TM module.

I think there was some work planned in 3.x to make the acceptance of variables more uniform in the scripting language. Do you think this could have been resolved already by that effort? If not, do you think it might be a reasonable feature request?

    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 :)
    
    Best regards,
