In spite of being switched off for the last 5 years it appears to be working. Using a standard 2-wire phone I can call other extensions but I can't program the system.<BR /><BR />The previous tenant left some Featurephones but for some reason took all the PSU's.<BR /><BR />I have the manuals but can anyone tell me what voltage the Featurephones need?<BR /><BR />Thanks for any help.<BR /><BR /> Sun, 28 Jan 2018 20:48:30 GMT Pjsaund 2018-01-28T20:48:30Z https://business.forums.bt.com/t5/Phone-system/BT-Inspiration-system/m-p/80243#M1848 Hi everyone<BR /><BR />I've inherited an Inspiration phone system with the building I've just bought.
