Hello Andreas,

I did two tests through the tapi browser, and I mananged to get the
disconnected event without actually disconnecting it myself. The first
one I rang a land line, I was messing about with some terminals when i
got the first disconnected event:

I cant understand why this is happening, but I am glad that I get the
same results within the TAPI Browser. Is this a hardware problem with
the modem? I have know idea.

Thanks for any help, Dene.
