If it works. The BBC having "fun" with VoIP systems is not the first
major installation that has had "difficulties". I guess they'll shake
the bugs out the core systems eventually but it doesn't appear to be
quite ready yet.

So what was the technology behind the internal 7xxx telephones at TVC in

If I remember the old contract correctly, you are required to return it,
not BT to collect it.

Dail phone - cancelling rental.

If I cancel the rental of my 'Basic dial phone' will BT come and take it
away or will they tell me that I can keep it?
The phone is old enough to have some value.

But can you get spares for them? We (Cambridge Uni) have just replaced our
15,000 handset PBX dating from 1985 with VOIP, because spares were becoming
difficult to find. And we'll save quite a bit of money by going to VOIP.

Crossbar (TXE) used to suffer from stuck reed switches, but the current

I'm on Virgin Media and twice I've had to tweak my MTU settings after
finding that about 20% of sites suddenly stopped working. According to
one forum it was something to do with an upgrade at the exchange.
As immoral and unethical Virgin Media are [1], I don't think they're at
the stage of blocking sites they don't like just yet.
