Orange box

Orange Orange Box
This method, informally called orange boxing, uses software that generates the audio signal which is then coupled to the telephone line during the call.
An orange box is a piece of hardware or software that generates caller ID frequency-shift keying (FSK) signals to spoof caller ID information on the target's caller ID terminal.

SIP URI scheme

In rare cases, a destination number served by voice-over-IP is reachable directly at a known SIP address (which may be published through ENUM telephone number mapping, a .tel DNS record or located using an intermediary such as SIP Broker).
SIP is vulnerable to Caller ID spoofing as the displayed name and number, much like the return address on e-mail, is supplied by the sender and not authenticated.
