Well i tried this on mine.
I called my Home phone (I pressed the edit button to check if it was set on telephone) and then ended the call.
Pressed green button to check dialled calls and it was still a picture of a mobile phone next to it.
But i'm not really bothered actually, Also my Firmware version is older than yours (V 03.70) so it looks like they didn't want to change it.
