[OpenSIPS-Users] use branches with uac_replace_from?

[Bogdan-Andrei Iancu]

Hello,

If you plan to change the FROM in different ways for each branch, you 
need to do the change in a branch_route and not in the request route - 
whatever changes you do in request route will be propagate in all 
branches. The changes you do in branch route will be vizible only in 
that branch. See:
http://www.opensips.org/Documentation/Script-Routes-1-10#toc2

So, in your script store the new FROM into an AVP variable and arm the 
branch route -> in that branch, if AVP is set, use it as input for 
uac_replace_from().
