Re: [asterisk-users] Multiple IAX2 Trunks Load balancing
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 On 12/14/13, 4:41 PM, Muhammad Usman wrote: Friends let me define the scenario please; Scenario: 2 asterisk servers (A B) are connected using 05 IAX2 trunks between them.

Hi, Generally, incoming traffic (http/mail/sip/vpn/etc) can easily spread with the random functions with iptables.

It sounds that you want to do the load balancing trick upon the application layer (eg. within asterisk) Perhaps it is possible to do the L.B. at the O.S. or network level, and let all trunks appear to asterisk to one single trunk. -- _ -- Bandwidth and Colocation Provided by http://www.api-digital.com -- New to Asterisk?

What resources are being balanced? 1) It's been said (but I've never experienced it) that IAX performs poorly at high channel levels. Something about all those packets being handled with a single socket (bound to port 4569). Maybe the OP is trying to distribute the load over a handful of sockets. 2) Maybe the OP is trying to distribute the load over different physical media. 3) Maybe the OP is just trying to develop a load balancing methodology. Multiple trunks between the same pair of hosts does seem odd. -- Thanks in advance, - Steve Edwards sedwa...@sedwards.com Voice: +1-760-468-3867 PST Newline Fax: +1-760-731-3000 -- _ -- Bandwidth and Colocation Provided by http://www.api-digital.com -- New to Asterisk?
