No, quite simply each of the prefix digits in the local exchange, would 
route back to the same routing case, which would be setup with the same 
charging record, effectively nulling the additional (non required) 
prefix

it would be really nice, if asterisk where possible kept the same 
naming conventions that have been used in "traditional telephony" since 
its inception. [For clarifies sake this previous sentence was totally 
tongue in cheek, with a tad of truth with no offense intended]
