[SR-Users] Changing $fU or $fn in branch_route

[Daniel-Constantin Mierla]

Hello,

assigning to $fn, $fu or $fU is offered as a convenience way to update
parts of From header, but the changes are not applied immediately, like
the other operations done over the SIP headers -- see more details in
the FAQ:

https://www.kamailio.org/wiki/tutorials/faq/main#why_changes_made_to_headers_or

In your case, try to do those changes only in branch_route.

Cheers,
Daniel
