as noted in asterisk/docs/README.variables (iirc)

you should see that variable inheritance can occur by prefacing the 
variable with '_' or '__'

also, depending on the age of your asterisk you might want to start 
using 'Set' vice 'SetVar'

also, having ${EXTEN:0} , the :0 doesn't do anything, so you should not 
use it and just have ${EXTEN}

i hope this helps
