Well, this is for a DID _range_, so if my DID range is 1600-1699, and 
the PSTN is delivering 4 digits, an incoming call for 1678 will then 
have my translation pattern stripping "16", replacing it with 3316 and 
then adding on the last two digits, so now the inbound call is 331678.

So, I'm deleting two digits and then essentially sticking them back in, 
except with two additional digits in front (my site code) which now 
matches my internal extension of 331678.
