Thanks Graham, there are not two devices on the same port, just one on
Sipgate, the other on Voipfone, on the two seperate ports of the
Sipura. Just to be sure, I disconnected one and checked the other, but
the problem is still there. I have noticed that the name on the display
blinks sometimes, so this might be the trigger. In the instruction book
it says the backlight goes off after 20 seconds, but I have now timed it
with the phone line disconnected, and it actually goes off after 30
seconds, so if I could find a setting triggering the phone before 30
seconds, and alter that setting to 35 seconds, then all my problems
would be over. ;-)
The dial tone appears to be the normal UK one on both phones, and I even
used the Voipfone automatic installation just to make sure that
everything was set as required.

I have just checked for 30 second timers and in the Regional settings of
the Sipura, I altered 'VMWI Refresh Intvl' from 30 seconds to 37 seconds
and that now seems to have enabled the auto backlight off, the cut off
time is variable between 30 secs and 3 minutes, but better than nothing.
I have no idea what VMWI is though, or why it should help, or if it
could cause other problems, so comments welcome on this please.
