How is caller ID spoofing used in VoIP calls?
Caller ID spoofing is changing the caller ID information so that it appears differently when you receive the call. For example, you might get a call from somebody but he is changing the caller ID to show he is calling from a bank. He might be asking for your bank credit card information. Caller ID spoofing is changing the header information in the SIP protocol to appear that it’s someone else who is calling.
