Make sure you are actually setting it as:

Set(CALLERID(num)=290XXXX)

The previous poster has the formatting incorrect. If your callerID is a 4 digit 
number, and you want to modify it to have the prefix on it before you send it 
back out, you can do:

Set(CALLERID(num)=290${CALLERID(num)})

Alternatively you could make the 290 a variable, then set it prior to calling 
the Set() application if you needed the prefix to be set based upon some logic.

Hope that helps!
