Hello

I have a normal analog phone and a modem going into a telephone T junction and
then into master socket to exchange.  The reason for this is I have problem
collecting the Caller ID from the serial port of the modem.  The modem is not
used for anything else.  to answer the call I use the ordinary phone.

Now the problem I have is that if I drop the call on my local phone the other
end doesn't seem to get a disconnection indication?  Their end just stays
'line' indefinitely.  If they have eg digital handsfree telephones and don't
drop their end they seem to stay 'live'.

I tried a few things.  I used ATH on the modem to drop the call - but this
makes no difference.

Any ideas why this would be happening?  Could different wiring affect it?

Any suggestions on how to send a disconnection 'indicator' to the other end?

Angus
