Ah yes, continuing the fiction that anyone who uses a VoIP service must be a fraudster with a faked phone number.
Just another in the long list of if you are not using Google or Microsoft e-mail and AT&T or Verizon or T-Mobile or Sprint postpaid mobile phone service, you're obviously up to no good and deserve whatever "anti-fraud" you get.
I might call you and check- and check for VOIP numbers, too, so no fakes.
