[OpenSIPS-Users] uac_replace_from/to on a Branch Route

[Antonio Anderson Souza]

Hi Bogdan,

Thank you very much for the explanation, I haven't understood that the
changes made in the main branch is inherited by the new ones.

I'll change my logic to concentrate the changes in the Branch route, and
provide a feedback to the list.

Thank you very much!
