I got a call from 650-284-0302 and decided to google it too (while waiting to see if they left a voicemail message)
By the time i got to this site, they left a voicemail and this is who it was from:
Messageware Inc - sales call
They asked me to call back at this number:
905-812-0638 x116
This is a product for Microsoft Exchange to "improve" Outlook Web Access email.
Just received a call from 650-284-0302 and the guy speaking with a heavy accent said he was from the Internal Revenue Service and had a package to deliver to our home. I asked him what the package was, and he said it was 5 million dollars and a TV. So, I laughed at him and hung up the phone.
