Hi Peter, I'm not sure how you are getting PSTN lines into your * box, but if 
it's not ISDN30, you might want to consider some of the cheap IAX phones on 
the market now rather than trying to soldier on with old analogue kit?

e.g. http://www.iaxtalk.com/product_info.php?cPath=1&products_id=29

Shipping for 30 units and UK power supplies was $340, and with the weak dollar 
right now, that works out at just over 40 quid per phone - I'm sure there's 
movement on the unit price when buying in bulk...

Now remove the need for an Asterisk Quad-E1 / T1 interface card and you've 
dropped the cost by nearly a grand.... food for thought :)

They also sell a single-ethernet-port version of the phone for $10 less if you 
have enough ethernet sockets.

Cheers,
Gavin.
