A sheet-processing machine includes a delivery, a guide surface for sheets being processed and a sheet brake in the delivery. For this reason, it is possible to maintain outstanding scalability of the system in a situation where the total number of settable numbers is limited. The first endpoint detects that the first call was placed on hold by the second endpoint and a second call between the first endpoint and a third endpoint after detecting that the first call was placed on hold. Another embodiment has at least one layer of polymer over the distal end of the device.
