I have had over 25 callers blocked same story. They call ask for my name then hang up.
What i found on my cell phone was a bit shocking. My firewall blocked port udp 8192
which is SpyTech Phone Service, also Sophos remote management system.
So the Indian Dudes calling you are asking to confirm via voice that you have your phone, they in turn email that to their customers showing that their remote software is in fact working. Here is a link to the software Oceans Edge. This is law enforcements way of not getting a warrant. Also see the ACLU website link. Save your wifi logs and communicate with your ACLU in your region. This should be treated as a freedom of privacy class action law suit.

Good Luck
Get a firewall with deep packet inspection so that you can view all the traffic coming and going from your smart phone while your on your WiFi network at home.
