It will have to be the latest rev,(did not think it was available for it yet though, only the tde/ncp, may be out in the USA) I haven't done one , but at the ncp launch they came up. as far as I know you connect up to 4 extensions and like the 2 ch cell that connects to the digital ext card it detects it is a dect cell. it will eat up extensions if you have to fit 2-3 of them.
Let us know how you get on
