Actually, it hasn't doing anything to the caller ID, it's assigning the 
first 2 characters of the CID to the variable.

No, that's what we're doing above.

Looking only at the first two characters of the CID and assigning it to 
${goaway} and then doing the testing on ${goaway}, leaving the CID intact.
