Ya I haven't really written one generally yet, but here is something I'm 
whipping together without testing :) I'll probably test it tomorrow during our 
daily documentation session.

[globals]
CUSTOM_RECORDINGS=/var/lib/asterisk/sounds/en/custom


[subRecordPrompt]
exten => _[A-Za-z0-9].,1,NoOp()

; Safely handle extension name -- this will be our filename
same => n,Set(RecordedFilename=${FILTER(A-Za-z0-9,${EXTEN})})
same => n,Set(RandomNumber=${RAND()})
same => n,Answer()

; Record the prompt
same => n(record),Playback(please-enter-your&vm-message&after-the-tone)
same => n,Wait(1)
same => 
n,Record(${GLOBAL(CUSTOM_RECORDINGS)}/temporaryRecording-${RandomNumber}.wav)

; Ask how we want to handle the recording
same => n(handle_recording),Read(ActionItem,vm-review,1)

; Verify we got values we expect
same => n,GotoIf($['${ActionItem}' = '1' | '${ActionItem}' = '2' | 
${ActionItem}' = 3]?valid_action)
same => n,Playback(wrong-try-again-smarty)
same => n,Goto(handle_recording)
same => n(valid_action),NoOp()

; Handle the recording
; 1 accept
; 2 review
; 3 re-record
same => n,GotoIf($['${ActionItem}' = '1']?accept,1) ; keep this recording
same => n,GotoIf($['${ActionItem}' = '3']?record)   ; re-record it

; If we get here they pressed 2
same => n,Playback(${GLOBAL(CUSTOM_RECORDINGS)}/temporaryRecording-${RandomNumber})
same => n,Goto(handle_recording)

exten => accept,1,Verbose(2,Recording accepted!)
same => n,System(mv 
${GLOBAL(CUSTOM_RECORDINGS)}/temporaryRecording-${RandomNumber}.wav 
${GLOBAL(CUSTOM_RECORDINGS)}/${RecordedFilename}.wav)

exten => h,1,Verbose(2,Cleanup the file)
same => n,System(rm -f 
${GLOBAL(CUSTOM_RECORDINGS)}/temporaryRecording-${RandomNumber}.wav)


...or something like that.
