I could be wrong but I think the callers just hear nothing when blocked. I have the KX-TG6845B/250 number blocking capacity.

They just tried me in Vancouver. The giveaway was that no location was shown beneath the number, but instead a repeat of the number was shown. Other people on this forum have said that this indicates a spoofed number.
I didn't answer it and no message was left.

Because this number called me persistently without identifying who was calling, I placed it on my blocked-list.

called me at 11:13 today. I answered within 2 rings and got dead air. Noted what someone above has said about how the numbers appear in the caller ID window, and will keep an eye out for this (and other) potentially spoofed number
