I use only 2 extensions at home. One is fixed phone (ext 100) and another one is my personal which I use to connect from my mobile phone client (ext 101). But I'm not allways connected with my mobile client so in situation like that I would like to forward all incomming calls to some external number. When I edit properties of ext 101 and visit "forwarding rules" tab I get options for Available, Away, out of office, etc... but I don't see "not registered". I belive there was "not registered" option in v8? Now I'm lost, how to to forward calls IF extension is not registered.
