So basically if there is a problem with line 1 out of 12, no calls 
are going to get through...surely this isn't expected behaviour.

Is there any way to fix this (I'm the New Zealand distributor of 
Digium products and if this is the case, they will be returning to 
their propreity pabx)?

Should I open a bugnote?

I spoke to a few people on IRC last night who confirmed that this is 
the case.  It seems crazy.  If I send a fax using a fax machine it 
works, if I dial a number with a modem it works (even a $5 modem) so 
why can't it work in asterisk?  It used to work on the X100P's...

I just want the card not to dial if there is no dialtone...
