Are you looking for something like this?
Note: This will continuously go between the two trunks until the caller
hangs up, can be fixed by adding loop counter.
;
; extensions.conf
;
[LOADBALANCE]
exten => _X.,1,NoOp(Connect to least used trunk)
; - show active count
exten => _X.,n,NoOp(Calls:
${GROUP_COUNT(TRUNK01CNT)}/${GROUP_COUNT(TRUNK02CNT)} of
${MATH(${GROUP_COUNT(TRUNK01CNT)}+${GROUP_COUNT(TRUNK02CNT)},int)})
; - goto least used trunk
exten => _X.,n,GotoIf($[${GROUP_COUNT(TRUNK01CNT)} <
${GROUP_COUNT(TRUNK02CNT)}]?TRUNK02,${EXTEN},1:TRUNK01,${EXTEN},1)
;
;
[TRUNK01]
exten => _X.,1,NoOp(Using Trunk 01)
; - set trunk used counter
exten => _X.,n,Set(GROUP()=TRUNK01CNT)
; - dial trunk
exten => _X.,n,Dial(IAX/T01/${EXTEN})
; - add loop counter to stop infinite loop
exten => _X.,n,NoOp(Use next TRUNK02is congestion or chanunavial)
; - next trunk if CONGESTION
exten => _X.,n,GotoIf($["${DIALSTATUS}"="CONGESTION"]?TRUNK02,${EXTEN},1)
; - next trunk if CHANUNAVAIL
exten => _X.,n,GotoIf($["${DIALSTATUS}"="CHANUNAVAIL"]?TRUNK02,${EXTEN},1)
exten => _X.,n,Hangup()
;
;
[TRUNK02]
; - same as above
exten => _X.,1,NoOp(Using Trunk 02)
exten => _X.,n,Set(GROUP()=TRUNK02CNT)
exten => _X.,n,Dial(IAX/T02/${EXTEN})
exten => _X.,n,NoOp(Use next TRUNK01is congestion or chanunavial)
exten => _X.,n,GotoIf($["${DIALSTATUS}"="CONGESTION"]?TRUNK01,${EXTEN},1)
exten => _X.,n,GotoIf($["${DIALSTATUS}"="CHANUNAVAIL"]?TRUNK01,${EXTEN},1)
exten => _X.,n,Hangup()
;
; - end

Friends let me define the scenario please;
Scenario:
2 asterisk servers (A & B) are connected using 05 IAX2 trunks between
them. The machine A is running asterisk & Openvpn server in TUN mode
(5 instances with difference IP addresses for clients). The machine B
is running asterisk with 05 OpenVPN clients using 05 bandwidths. The
IAX trunks are established between each pair of P-2-P ip address of
machine A (The OPENVPN Server) & machine B (The Openvpn client).
Requirement:
Required dial plan configuration at machine A for incoming calls from
VoIP Switch/VOS which can forward the calls to IAX2 trunks in round
robin fashion like Load Balancing. If any trunk goes down it starts
forwarding the traffic to other available trunks & when it gets UP the
dialplan should perform as desired. Like L.B & Fail-over scenarios.

Perhaps the O.P. can explain about his intentions...
In some situations it makes sense though:
If you have to connect two servers, and use different kind of
infrastructure / multiple providers...
