We definitely don't have any 2 channel ISDN (at least not connected to the phones - there are several of them that BT/Thus use for monitoring our LES circuits and for companies that use them for remote support) but our phone system is connected to an ISDN 30 but there is also an ntl/Telewest line (DASS??) which can provide another 15 channels as overflow for outgoing calls (I think - I don't really get involved that much with this bit of the phone system)

Sounds like you've just got a second isdn30 line, except it's supplied by telewest, not BT.

See it wasn't me being stupid! I know ISDN30 starts at 8 channels - looks to the wall and spots the nice ISDN30 box - isn't it spookey how BT use the same NTE unit for many many different uses - ISDN30, Leased Line, VPN Connection that I had in my last place to the county etc it must be a very adapable NTE!
Anyway glad we got that one sorted
