One of the methods suggested to get around this service was using a calling card.
To my surprise I was informed by a coworker that sometimes calling card services also forward the ID.
Bottom line is that caller ID & caller ID blocking have been with us long enough for people to take them for granted.
I for one had no idea that the block worked on the receiving end and not the sender.
I also did not know that 800 numbers could view the data.
Any time you provide a tool like this, it has the potentiall to be used against the owner as well, especially if someone else with access to the equipment understands the tool better than the owner does.
I can see several scenarios, some more plausible than others where another party might be inclined to use it to lock the owner out of access to his own data.
Yes if the other party has access to the machine, they can always cripple it by other means but the beauty of this is that it can be used even after that party apparently no longer has access.
