I don't really get what you mean. Do you need a solution for an older
version? openser was the old name for kamailio, all modules that existed
during openser name are in modules/ or modules_k/. Starting with 3.2.0,
you can directly assign value to $fu, previously the solution was to use
uac_replace_from() of uac module, or play with functions from textops
module.

Do you get any error messages in the log where it does not work? Add
some xlog(...) to print the values used in the operations. debugger
module may help you to see if the action is actually executed.
Btw, if you need the From header to be reverted in the reply,
uac_replace_from() is the better way to go.
Cheers,
Daniel
