Don't bother with 'privacy manager'. For me it is totally useless. The only thing it EVER has stopped was Vodaphone/Vonage calls that use weird caller IDs, like 000-000-0000. It blocked my attempt to check my messages when I called from Scotland and ATT uses Vodaphone for their wireless over their.
They called today and they didn't leave a message. Got another call not a minute later from another number that we blocked so I'm pretty sure it's the same bums. That other number is 901-300-7420. Even though that's a Memphis metro number, you can be sure these creeps are not in the city where their caller ID has them.
I keep getting these calls to install a security system. When I started answering the phone by saying Detroit city Police Department the calls seem to not come through as much
