A different approach to that problem:

#define local_folks nancy|jim|james

exten => local_folks,n,Verbose(1|My current EXTEN is ${EXTEN})
exten => local_folks,n,Playback(silence/1&tt-weasels)
exten => local_folks,n,Hangup()

I sometime find the n priority still confusing and unintuitive, Though 
that "p" is not auto-incrementing and hence less confusing.
