Well, in this case the subscriber is also the telco!

You're right, when someone answers it's not a problem. But if the caller
is sent to voicemail and he hangups, we get 30 seconds disconnect tone.
Or if the caller is sent to a queue and he hangs up, the agent takes a
call which is already hung up.

Yes, I already looked for such a configuration option, but unfortunately
couldn't find any. I hoped someone on the list had experience with a
Mediatrix on Euro ISDN.

No problem understanding, maybe because English is not my native
language either ;)
