About Caller Id Forging/Spoofing
Caller ID Forging the practice of causing the telephone network to display a number on the recipient’s caller ID display which is not that of the actual originating station; the term is commonly used to describe situations in which the motivation is considered nefarious by the speaker. Just as e-mail spoofing can make it appear that a message came from any e-mail address the sender chooses, caller ID forging can make a call appear to have come from any phone number the caller wishes. Because people are prone to assume a call is coming from the number (and hence, the associated person, or persons), this can call the service’s value into question.
Basics of Call Forging
Firstly the voip is used to call via internet PC to a telephone.
In the Voip there is a loop hole which allow a intruder to spoof a call.
There are many website on the net which provide the facility of the internet calling.
This website work as follows,first the call the source phone no then the destiation number and then bridge them togather.
Here there is no authentication done by the website and server are normally located in US and so tracing of the intruder is not possible.
Thus the intruder logs on to this server and gives a wrong source number and then place a call over internet which is actually a spoofed call which shows wrong identity.
Also there a no laws regarding the call spoofing in India and so a intruder if gets traced is easily backed by the loophole of no laws for it.
thus if you get calls from other numbers don’t trust it they may be spoofed calls.
