Thus the recent FCC warnings about dialing back unknown "local" numbers. Thus, "be careful about calling back".
A couple weeks ago, I received a call that, on my cell, very obviously came from the 20 country-code. However, on my VOIP line's handset - and its simplified display - the number simply appeared as a ten-digit 202NNNNNNN (the 202 area-code is local to me) number.
