We just got hit with this. Didn't relize that was the problem with the phone. Lot of hangups and unusual call volume when no one was at my store. No mention on how to fix this. How do we fix this., what does my phone service have to do to stop these calls from coming in.

Sorry for the slow reply. We have solutions that monitor for these call pumping attacks and block them at the edge of your network. If you are interested, contact me at
