What an אנשיקעניש. I probably blocked already 50+ phone numbers from him on my landline, but he always manages to get through with new numbers. And for cell phones if you block it'll spam your voicemail. He likely makes money from tmimesdiga bubbys who have enough time not to become intimidated.
The phone calls go through Voice Over IP systems, which one can easily setup - and it takes a second to change your caller ID to any number you wish. I once had somebody who never picked up my phone calls (because he owed me money), so I changed my caller id to his home number and called his cell phone number. He answered right away, thinking that it's his wife.
