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.
A rolling disk gathers no MOS.
