[Kamailio-Users] from replace

[Gentrice's kaiser]

daniel,

I have tried use it in branch_route only too and xlog to see the value,
xlog shows everything fine,
but still no good result, from is still redundant..
I even try to write a simple script  just to verify this feature, but  
the same result ...

I will paste the script later.
