BMP:SPAM telephone caller number sharing system   Disclosed is a idea for sharing called telephone number.

ANI (Automatic Number Identification) or "Number Display" is a widely used service.

Once a telephone user have a marketing outbound call, the user will register the called number to using telephone by using ANI.

From next time on, when the user have the call, the call from same number will be rejected. This idea is already implemented by some telephone devices.

The problem is, this idea is not so effective since there are a lot of outbound marketing call companies.

My idea is registering called number to IP-phone service provider.

If the number is shared among IP-phone users, it's much more effective to avoid having marketing call.

Sharing call history among users will give effectiveness to avoid unwilling telephone call.
