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.
Since ID's cannot be blocked when the recipient is an 800 number, they allow their clients to forward incoming calls to their service. The caller ID info is then collected and forwarded along with the call, back to their clients.
Advocacy groups for victims of domestic violence are concerned.
Victims of annoying calls hiding behind caller ID blocking rejoice.
