I have a simple rule - on my work number I NEVER take calls from a number that I don't know given the fact that I ONLY give it to people that need to have it. I know from experience that most scam calls and telemarketers use the dialing prefix 087... Some *ssh*le called me on workline from this number and let the phone ring for 15minutes (I have identi-call on my phone so I didn't answer) I simply turned the volume down and let them waste their stupid time hahahaha....DONT CALL ME ASSHOLE
