[Asterisk-Users] Zap Channels

[FaberK]

Hi guys,
on my Asterisk box I've got 3 PRI, and I need to use 2 of those, with
one guest, but I see that only the 3rd is used.
This is what I've put into my extensions.conf:
-------------------------------------------------------------------------------
[trunk]

exten => _7653.,1,SetCallerID(${CALLERID(number)})
exten => _7653.,2,Dial(${PRITRUNK2}/${EXTEN})
exten => _7653.,3,Dial(${PRITRUNK3}/${EXTEN})
exten => _7653.,4,Congestion
------------------------------------------------------------------------------

What's wrong?

Thanks!
