Script Description

The sip-call-spoof.nse script spoofs a call to a SIP phone and detects the action taken by the target (busy, declined, hung up, etc.)

This works by sending a fake sip invite request to the target phone and checking the responses. A response with status code 180 means that the phone is ringing. The script waits for the next responses until timeout is reached or a special response is received. Special responses include: Busy (486), Decline (603), Timeout (408) or Hang up (200).
