A BIG H/T to Techguru on MilePoint for this one.
Trapcall is a subscription based service for mobile phones that unmasks blocked caller ID. One of my peeves is the anonymous caller ID and it looks like this will eliminate it. One of the features of trapcall is that you can blacklist unblocked phone numbers which really will help reduce the amount of times I pick up the phone just to hear a sales pitch.
There are 3 levels of service, and pricing varies accordingly. You can learn more at www.trapcall.com
By the time you read this, I will be a new subscriber!
