Newbie question on dialplan

Hi guys,

i’ve going thru asteriskTFOT ebook, i don’t quite understand this part, would any kind soul enlighten me this portion?

For example;

[globals]
OUTBOUNDTRUNK=Zap/4

[outbound-local]
exten => _9NXXXXXX,1,Dial(${OUTBOUNDTRUNK}/${exten:1})
exten => _9NXXXXXX,2,Congestion()
exten => _9NXXXXXX,102,Congestion()

what is the purpose of having “102, congestion()” when you already have “2,Congestion()” ? 102 stands for priority right?

Thanks alot!
Cheers,

  • jumps to exten + 101 when busy, it goes to next line if call fails
