Sadly it is not likely it will ever work. I've used BT VoIP boxes, with
PSTN connectivity, and they work with a relay. They are on VoIP all the
time, unless there is a power cut, or the user presses a key which has
been assigned. When a incoming call comes through on a BT line the CLI
is sent before the ring voltage, the relay does not switch over until
the ring is sent. So if your using a cable line (with american CLI) it
will work, because the phone rings, the relay clicks over, the CLI goes
thru, the phone rings again. I don't know if what i am blabbering on
about will help anyone, but BT CLI is not good with VoIP to PSTN
connectivity. Best to use an additional telephone :)
