Called, didn't leave message. I'd never heard of them, don't know why they called. I found out by calling them back the name of the company. "Gravin Austin & Drake"
Called my work phone # (I am a temp employee and as a rule do not answer out-of-state calls since my job does not require it). Left no message.
Caller ID says "GAD", As one other user noted there is a telemarketing firm Graven Austin Drake located in Colorado Springs. According to their website, "GAD boasts over 20 years of documented success with outbound telephone campaigns."
