its customers. To activate, customers are required to call the
service provider and request the specific feature.
In most situations, customers will be directed to dial *60 from
their landline phones. If successful, you are connected to a
recording, confirming that the call blocking feature is live on
your landline phone service. If this has not yet been enabled,
you are then prompted with steps to activate.

features, they now have to go through the tedious process of
actually adding the specific phone numbers you want to

enter specific phone numbers you would like to block using your
landline phone. On top of this, most service providers have a

Panasonic Call Blocker only stop 5% of unwanted calls.

still get through?
