perfect bar the £180 price tag!

a few years ago I saw something in one of those little catalogues that has things in for the old or disabled. It was a cordless phone that plugged into a landline and used the landline number, but if it was out of range of the base unit it would convert to using a sim card and a mobile provider.

surely you could make it out of range by unplugging the base unit.

If it's the one I'm thinking of you mean the Dolphin system, used your house as a landline until you were out of range then used the Dolphin aerials dotted around the area.

They went bust some time back.

If it would work for you you could always use the wireless phone from Vonage, it uses any open (or secure if you know the key) wireless internet connection to make and receive calls. Costs about £6 p/m and you can have any area code you want.

I use them for VOIP and have found them to be very reliable.
