Don't know this number. My call blocker got it. I don't return blocked calls. I've been getting calls from all over the country for weeks, never the same number twice. They never call back. The first call was from a telemarketer, I told them I've been on the Do Not Call List sense 1992. This no longer dentures them. After the third call, I put a call blocker on my phone. But even that dosen't deture them. The call blocker has give me peace of mind.
