Initial requests sent to a Contact address rather than being sent to
an AoR are always problematic. The same occurs in attended trasfer
when the REFER is sent within the dialog and contains a Refer-To with
the endpoint Contact URI. Such URI could be no reachable if it's
between some kind of NAT's (regardless the user used STUN).
