There's no such thing as a ephone or ephone-dn in CCM.
CCM has phones (actually device/phone), phones have lines, lines get DN.
CME has a lot more versatility, with its feature of emulating key
systems and PBX systems or hybrids. You get shared line appearences here
(same DN in many places) where in CCM you sort of do that by pilot
numbers and a helper application. Just wanted to highlight that CCM and
CME are different beasts with confusing names and overlapping
application domains.
