when I signed up for alexa calling, I used my google voice number. today after the latest alexa update I was exploring the new and click on contacts. found it is using my real att phone number contact list but it also added Potential Fraud, telemarketer, and suspected spam numbers to that list. don't have the slightest where they came from other than I know they called me but I never answered. they are not in my phones contact list nor in my google voice contact list. things are going to get fun trying to figure it out...
