Just a word of warning to anyone buying a 'new' BT Voyager 220V router. Please be aware that these are supplied by BT locked & can only be used with a BT broadband account. Unless they are advertised as 'unlocked for use with all ADSL ISPs' you cannot use them on any other ISP, even if ADSL. These routers will not work on cable, nor can the voice function be used on any ISP but BT even after unlocking. It may be possible to unlock these using hacked software available online, but this is risky because if the installed version is later than the hacked one, then you may ruin the router.
