asterisk users - Mar 2004 - UK BT caller ID revisted

Hi all,
Does anyone know the procedure for adding a serial output to a cheap caller 
display unit. If I can find a way of doing this then I'm sure there will be 
away for linux to take the CallerID info, write it to a file, * to open that 
file an read the number from it.

TIA
Jon

I am going to a Radio Rally tommorow and I will buy a couple of stand alone
Caller Display units to strip and get a serial output from them.

Watch this space.

Sorry I never got round to answering your previous request - I will
write up
what I have done with asterisk in due course.

In the meantime, there's some good info on hacking CID boxes here:
