I have an older single line analogue, single button Pantel doorphone that is working fine with a Cisco UC320W on its analogue port.
However, it does not detect disconnect, and the person at the door gets to listen to around 40 seconds of number busy after the doorphone press has been answered by a human and the call terminated. Is there a way to fix this please?
I am not sure whether this is a Pantel issue or a Cisco issue so have also posted on Pantel customer support website!
