Hi Marco,

there is no such support for the moment. VIA and Contact are key routing elements and playing with them might get things broken. also you have to consider that contact is a per-dialog information and if you change it, you need to remember the original value across the entire dialog.
So I understand that it is not possible to prevent real UAs address contacts from being forwarded to far end users. If you confirm this, do you think of any workaround?
currently you cannot do it - neither for VIA, nor for Contact and RR/Route.
but in the future, with quite some development, it might be possible. For example the dialog module may offer a good support for Contact and RR/Route hiding since it offers dialog persistence.
