We receive calls from this number at least once a day. The caller id shows our local area code prefixed to the number along with 011+, like this +011 512-100-2350. Probably an inbound international call with fake caller id info. I can't block the number and they never, ever leave a message. Since it's likely coming from an overseas location it would best to never answer the call.

These people call from numbers that are obviously not real numbers. We can't block them or get their name, and it is for a wrong number
