How then does a users phone dials this. I have never seen a phone with + 
on the keypad, nor have I ever seen dail plan logic in a phone that 
could correctly handle the variable length issue of international 
numbers in order to do a rewrite and send the + in front. I work mainly 
with Cisco and Aastra phones but I have never once seen a user dialed 
call ever have an actual + instead of the code that the meta  implies. 
In fact the only reference  I could find to + being an actual character 
is on GSM networks. Still the user would have to use a special input 
mode to dial this as it is not on their keypad.
