While my 5-star rating is "proforma" at this time (haven't purchased this yet, but I've based that on my opinion of the device from what I've read, minus my knowledge of Sprint coverage and customer service), I'm simply posting to let the previous reviewer know that this unit appears to provide a clock and call timer, as well as advanced display features such as "Group Conference." Check the owner's manual, which Amazon has conveniently provided for download.
