[Asterisk-Users] Caller ID fake-out tool

[John Todd]

This (fraud?) was brought to my attention today.  An interesting 
idea, I don't know if it's genuine or not, as I have not purchased 
it.  What interests me more is the concept behind the product: the 
ability to generate CID tones after-the-fact in order to populate 
caller ID devices with customizable data. It plays (supposedly) a 
series of tones that simulate the CID tones to which many caller ID 
boxes listen. If this is a viable idea, perhaps it could be written 
into Asterisk as an application or extension.

Downsides:
   - obviously only changes CID after call recipient has picked up call
      - probably plays loud modem (Bell 202?) noises into the call
      - the "real" caller ID is still in memory of the call 
recipient's caller ID system
      - will probably not work with PBX systems that take CID and run 
with it, and ignore further updates

Upsides:
   - would allow me to use multiple analog lines with consistent 
outbound appearance
   - would allow me to overflow CID buffers to remove my original CID 
with junk (marginally useful)
   - ? others
