This is propably something we need to change and make the To and From headers writable.
It's not dirty to change them any more.

David: In the original SIP 1.0 protocol the To/From headers was part of the dialog identification, thus you where not allowed to change them in a proxy. THis was kept in RFC3261 - sip v2 - but has been removed in an additional RFC a short while ago (seen from SIP history).
