Just to be clear, what is the exact "disconnect problem" that you see?

I have three TDM cards in two different systems, one using PBX lines and 
one on a private BT line.  Both of them have trouble detecting a caller 
who is ringing, but then hangs up before being answered by the asterisk 
system

However, *all* of them are absolutely fine at spotting a normal hangup 
once the call is connected and I see no random disconnects during calls 
either.

Can you confirm that this is what you mean, or whether it's something else?
