I answered on the 2nd ring, no conversation. No response after I said Hello 3 ro 4 times. I hung up. If it's automated, it's probably a telemarketing call. Those I don't have time for.
This is one of more then a dozen numbers from the same area code and prefix that calls my cell phone, leaving no message on voice mail or not speaking when I answer. Even though I said hello 3-4 times.
