${EXTEN:2:3} says:

Start with an offset of 2 and dial the next 3 digits.  Offset 0 is the 
first 1, offset 1 is the second 1, and offset 2 is the first X.  This 
will simply dial XXX not substitute the first X for a 3.  You would need 
something like:

exten => _11XXX,n,Voicemail(3${EXTEN:3:2}|su)

Not sure why the mailbox for 127 isn't 127, but you probably have your 
reasons.
