Not trying to second-guess my esteemed colleague Ed, but...

Their website states that they have sold "millions" of these telephones. All the copy implies that these are plain old telephones, usable on all the PBX's in the world. I can't think of a single PBX that rings on 48 Vdc. Have you Googled the user manual? It says that the phone has a REN. That would imply that it is compatible with the PSTN. Does the phone have a red message Waiting lamp? Does that lamp illuminate steadily while the phone is ringing steadily?

My prognosis: You have acquired a defective telephone. Did you perhaps find it in a dusty telephone room at some motel, and it jumped into your car when no one was looking? Probably it was defective long before you...ahem...liberated it.
