BT so you probably have a point.  To be fair to BT I'm not saying that
the ISDN does drop during power outage
I was simply speculating on the reasons for what I was told, I suspected
that this was old wives tails.

This is what I assumed but since couldn't base this on experience I
bowed to louder mouths

>> Man, you must have nice and quiet customers. 

I think the reason they are quiet is because historically they haven't
had phones without power.
Further to this I bet they were simply told by their old school PBX
provider that such things were
"black magic" and not be used.  :-)

Thanks for clearing this up and confirming what I believed.

I think I will look into adding a UPS and connecting the * and the ISDN
wall box and maybe a handful of the DECT phones and the reception
phones.
This will be a nice mix between cost to functionality I think.

Cheers

Alex
