[Asterisk-Users] Altering Incoming CallerID

[Hugh L. Johnson]

What do I need to do to alter incoming CallerID?  The below isn't
working...

Running Asterisk 1.2 CVS HEAD

exten => NXXNXXXXXX,1,Wait(1)
exten => NXXNXXXXXX,2,Set(CALLERID(name) = "Fred")
exten => NXXNXXXXXX,3,NoOp(${CALLERID(name)})

 -- Executing Wait("IAX2/A-9", "1") in new stack
 -- Executing Set("IAX2/A-9", "CALLERID(name) = "Fred"") in new stack
 -- Executing NoOp("IAX2/A-9", "Hugh Johnson") in new stack
