Consumers get so many spam calls that they ignore most calls or use voicemail to screen calls, but for people who have to expect inbound calls (sales, customer service, etc) screening isn't a good option. This forces a segment of consumers to blindly field calls.
Solution
A mobile application that captures the inbound caller ID and runs it through multiple services to capture and evaluate who is calling. Additionally, allow for more intelligent screening services to gather information before taking the call - an AI virtual assistant.
