Actually that was a PMBX (Private Manual Branch Exchange). One where calls
are dialled direct by extension users is a PABX (Private Automatic Branch
Exchange). Both of these connect to the public (PSTN/POTS or whatever you
want to call it) network. An internal automatic system which has no
connection to the outside world is a PAX (Private Automatic Exchange).
These were once very common, particularly in larger organisations, where
you would have a PMBX to handle external calls via the company operator,
but an automatic system for internal calls. You could always tell where
one of these systems was in use as there were two phones on every desk,
one on the PMBX (often with no dial) and one on the PAX.

Not really, it depends how many phones/lines you have..!

What an awful name, why on earth did they change it..? What was wrong with
Asterisk..?

Most of this thread could of course take place in uk.telecom, unless the
OP specifically has VoIP solutions in mind.
