Caller ID is an easy way to hide your phone number.
A long time ago you were able to call someone without having to think about whether or not if the person on the other line would pick up.
If you did not answer then you would be left to wonder who just called you. You just had to sit and wait for them to either call back or never know who called at all. This was a dilema that would be over come with time and technology.
Soon, the caller id would be born.
Caller Identification is done by one service talking to another. The details from whoever is calling is then matched with a big phone book which then tells your phone who is calling.
This was fantastic for awhile and then came VOIP. Voice Over Internet Protocol. This technology allows for someone to call over the Internet using the same data transfer as a computer would but instead of sending emails etc…You are now sending your voice over the internet.
You are Wondering what does this have to do with caller id?
It has a lot to do with it
A great deal of people these days do not pick up their phone when they do not know the phone number.
This is almost always due to the fact that person on the other end is looking at the phone caller identification and making a fast decision on whether or not to answer to your call.
But due to VOIP having the ability to hide your caller identification it then become a dominate player in the faking of your caller identification.
This card gives you more of a opportunity to get someone to answer the phone by making it look like someone else is calling. So you can be anyone you want to be, even the Elvis.
This advantage has it’s bad and good points and should not be misused.
