How does that work if your handset is switched off? Is the divert
registered at whatever (foreign) network the handset was last seen at?
Or does voicemail when the handset is on (using the handset's settings of
wait-N-rings, divert-straightaway, whatever) differ from when it is off?
Is this state then stored in the network somewhere - at your network, or at
the foreign network? If it's at your network, why can't it just divert
without an international round-trip?
