asterisk users - Mar 2003 - extensions rules

Hi guys, I need a hand with extension rules. I just finished the old 
manual but after doing some test I'm not sure about the sequence of 
greeting/hold music/and so on. It's supposed to play a greeting and 
read a menu of options, then try the extension and record message.  
I understand what each line item is but what got me confused is how 
the priority number jumps back to 1 when it lists te extensions. 
What are the exact rules here? When is it OK to decrease priority 
and why would you?

Example:
exten => s,1,Dial,Zap/2|5
exten => s,2,Voicemail,u100
exten => s,2,Background,demo-thanks
exten => s,3,Goto,2
exten => s,4,Hangup
exten => 1,1,Voicemail,u100
exten => 2,1,Goto,s|4
exten => i,1,Goto,s|2
exten => t,1,Goto,s|2

Think of priorities as line numbers in Basic, but with out gaps.

[example]
exten => s,1,answer
exten => s,2,Background,Your_greeting_file
exten => s,3,Background,Your_menu_file

exten => 1,1,Dial,Zap/2|5     ; maybe this should be longer
exten => 1,2,Voicemail,u100   ; unavailable fall through
exten => 1,102,Voicemail,b100  ; Busy skip n+101

exten => 2,1,Hangup

exten => t,1,Goto,s|3

exten => i,1,Goto,s|3



Hope this helps clear it up.
