i think the point may be that there can be massive prefix lists and
folk don't want the extensions.conf from hell.  it would be a nice
hack to have an external utility to load one's named [0] prefix
lists into something that can be used for matching analogously to



[0] - named so one can have more than one.  i have out-dials in
      four locations each with a non-trivial set of prefixes.  so 
      i kinda wanna do

      exten => biwa.,1,Dial(SIP/${EXTEN}@biwa0,60,Ttr)
      exten => hawi.,2,Dial(SIP/${EXTEN}@hawi0,60,Ttr)
      exten => marais.,3,Dial(SIP/${EXTEN}@marais0,60,Ttr)
      exten => tokyo.,4,Dial(SIP/${EXTEN}@tokyo0,60,Ttr)
      exten => _.,5,Dial(SIP/${EXTEN}@fallback-provider,60,Ttr)

      and let some external process/cron/gui/... keep the four
      databases up to date.
