Could you please post your extensions.conf section that references how 
outbound calls work?  My assumption would be that you are only 
referencing one of the zap interfaces and should either be using a group 
or listing the zap interfaces sequentially in the dialplan so that if 
the first one is in use the second one will be used.

Example of using a group would be, in zapata.conf for the lines you are 
trying to dial out on:
group=2

in extensions.conf:
TRUNK=ZAP/g2

exten => _NXXXXXX,1,Dial(${TRUNK}/${EXTEN})
exten => _NXXXXXX,2,Congestion

Doing it without a group would work as follows:
exten => _NXXXXXX,1,Dial(Zap/1/${EXTEN})
exten => _NXXXXXX,2,Dial(Zap/2/${EXTEN})
exten => _NXXXXXX,3,Congestion

Using a group lets you setup several lines to be used when the group is 
referenced.

More complex than you probably need but the letter used when referencing 
the group will change how the group works:
; g: select the lowest-numbered non-busy Zap channel
;    (aka. ascending sequential hunt group).
; G: select the highest-numbered non-busy Zap channel
;    (aka. descending sequential hunt group).
; r: use a round-robin search, starting at the next highest channel than 
last
;    time (aka. ascending rotary hunt group).
; R: use a round-robin search, starting at the next lowest channel than last
;    time (aka. descending rotary hunt group).
So Zap/g1 starts at the lowest line and Zap/G1 starts at the top of the 
available lines, etc....
