Ringing (telephony)

ringingmagenta boxcall bell
The vermilion box incorporates three more basic phreaking boxes: the magenta box, which generates the AC ringing signal required to make the target telephone ring; the orange box, which generates caller ID (although it is not a proper call-waiting caller ID orange box that is used but a modified orange box that generates on-hook (idle state) caller ID); and the beige box that is used to conduct the actual conversation.
A magenta box in conjunction with an orange box (which emulates the caller ID signal to create falsified data) is called a vermilion box.

Orange box

Orange Orange Box
The vermilion box incorporates three more basic phreaking boxes: the magenta box, which generates the AC ringing signal required to make the target telephone ring; the orange box, which generates caller ID (although it is not a proper call-waiting caller ID orange box that is used but a modified orange box that generates on-hook (idle state) caller ID); and the beige box that is used to conduct the actual conversation.
One proposal to accomplish this involves an orange box used in conjunction with a magenta box, which in combination is called a vermilion box.

Vermilion

The vermilion box is named, following the tradition of naming phreaking boxes after colors, for a color (vermilion) that is similar to a combination of the color names of two of the component phreaking boxes from which this box is made: orange and magenta.

Ringdown

In theory, a two-line adapter configured for ringdown (where taking one side off-hook causes the other to ring, displaying a pre-configured caller ID name or number) could serve as a line emulator, requiring only a handset and DC power source.
