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.
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
