Caller type: Unknown
Not sure what the call is about seems like they want some personal details via a IVR command prompt. I get the feeling any voice activity would automatically send me to a live person which would then give some scripted response regarding building some type of application or service that I have no idea about. My number is not given out without my knowledge which was obtained from some data sweep a vendor might use to sell in bulk without my consent.
