In the past week I have been getting hundreds of calls that have numbers like +89284726182 or other "+" numbers with 11-12 digits each. 99% of them do not leave a message, but a few have been people with what sounds like indian accents saying "I am calling your to discuss your frustration with underperforming clients" or something. I have Hiya installed, so they all go to some kind of block or screening, but this pattern is new and the volume of them is very high. It might be domain related as I seem to get them on the number I use for my domaining contact, but not my other phones. This is not related to calls I usually get after regging with NetSol, as those appear to be real numbers and only come in small bursts.
