Now though he can literally hangup, use his phone and then
reconnect and if use netstat throughout the ordeal, my computer
never notices any type of loose of connction. Basically is this
expected/acceptable behaviour.

Yes it is, if the applications at both ends don't time out in the mean
time due to a data transmission or a keepalive probe. In fact people
with modem links sometimes depend upon this to keep long ftp transfers
going if their modem should hang up in the middle, and some
administrators argue against it because it keeps connections around
when users's PPP links go down.

In any event, the behavior is staying, at least certainly as the
default, as the standards and all existing implementations I know of
do it like this as well.
