Hi - I have 2 Asterisk servers connected using 05 IAX2 trunks. I want to load balance incoming calls over IAX2 trunks. If any trunk goes down the calls traffic will be shared with other available trunks. When it gets Up the script is supposed to perform as desired i.e in load balance mode.



Thanks in advance.

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.

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 TRUNK02 is 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/${EXTEN})
exten => _X.,n,NoOp(Use next TRUNK01 is congestion or chanunavial)
exten => _X.,n,GotoIf($["${DIALSTATUS}"="CONGESTION"]?TRUNK01,${EXTEN},1)
exten => _X.,n,GotoIf($["${DIALSTATUS}"="CHANUNAVAIL"]?TRUNK01,${EXTEN},1)
exten => _X.,n,Hangup()
;
; - end
