Hi, I'm looking to update my current landline handset and I was wondering if it has to be plugging in to my BT router to work or can it be plugged in to any 3-pin electrical socket and or a phone socket (normally white with the sliding door over the connector).
I'm looking to use a multiple cordless phone system so I can be in any room instead of sat by the router as I currently am when I use the phone.
