I've gotten a call a day on average from numbers very similar to this (2999, 2989, 2990) for two weeks. They seem to switch up the phone number every few days and the caller id name almost every call. Sometimes it's telcom cust serv or cs, other times it's V followed by a dozen or so numbers. I'm beginning to wonder if I can block the entire 508-556 exchange.
