Me too .. once I picked up to hear a male voice saying he is from Allianz Insurance

Its an insurance company.

Missed calls at least once a day for the last couple of months from this number during the day on the home phone while I am at work. Have never left a voicemail. Have no idea who it is. SO annoying.

I have been receiving calls once a day for the last 2 weeks from this number. If I answer, it hangs up. I have now stopped answering in case it is costing something. I also don't want to call it back in case that costs something too. It is getting very annoying!
