Caller 4/6/15, 6:54 PM PDT. Caller ID "showed "Lancaster CA" and this number. Know no one in that area, nor business dealings there. My phone answered by Sentry robo call blocker which advises calling party we do not accept calls from telemarketers, to remove our number from "their call list" (legal requirement to ever prosecute them), or to Press 0 to leave message. No message left. Various reverse call searches only show as a land line in that city.
