I was my impression that no phone could be kept connected by an outside originated call for longer than about 30 seconds if it the called-to phone was on hook. An outgoing call from your phone *can* be disconnected if you hit *your* switchhook for a few seconds, but the person you are talking to has to hold their switchhook for 30 seconds to disconnect the call. Besides the annoyance factor, isn't this a safety risk if you have to dial, say, the fire department? It would be very counter-intuative to leave the phone on hook for a long time while waiting for a dial tone if it was a panic situation. Further, if you happened not to wait long enough, the 30-second cycle would resume and the time you did let it sit on hook before would have been wasted. I think this topic has been covered on the internet RISKS group, but it would have been a while back.

According to a discussion in mod.telcom a while back, this is a feature
intended to make it possible for you to move to a different phone to carry on
a conversation. I imagine that in this day of digital switches some code
could be arranged to allow nearly instant disconnect from the callee's end.
Someone, of course, would have to make it advantageous (read: raise hell).
