this is actually a great topic.. I understand completely, and would love it if my dispatcher(s) could just see where I am instead of calling to ask. I have thought about trying to push the issue, but it's cases like this that made me hold off.
also nobody mentioned the carrier's potential liability. shouldn't the user still have control of somethings even though it's on a busness account.. I'm assuming the user can't log into the site.. I don't remember being able to, but that was several years ago. my account now.
to me if life were perfect you & "the business" could "agree" on the site to work hours, and outside those hours you only get txt/vm..
heck, they could even sell it as a "time-clock" service.
