Well, I was suggesting an OPTION to disable the detection after a specified period, so anyone who wishes to do as you describe could just leave the setting to indefinite if they wished. Having said that, I don't think that sort of behavior is particularly common anymore. More importantly, I would argue that practically all users doing that are, as you mention, using a phone connected to a fax machine, eliminating the usual needs for sending the call to the fax extension. 

Either way, if defined as an option, users could choose how they wanted it to work.

While that might be true, false detections are anything but unheard of, so being able to disable detection after the first few moments of a call might be useful.
