Like to report back, in case anybody bumping to the same problem. After digging more and looking at debug log. Apparently the culprit is on the way I set channel variable. On my case, dialstring should be : <action application="bridge" data="{ignore_early_media= true,fail_on_single_reject=^^:NO_ANSWER:ALLOTTED_TIMEOUT}[leg_timeout= 20}]sofia/gateway/gw1/7321231234|[leg_timeout=20] sofia/gateway/gw2/7321231234|[leg_timeout=20]sofia/gateway/ gw3/7321231234}"/> Once that in-place, it work as expected. Thats all, my bad, Freeswitch Rock!! On Fri, Oct 18, 2013 at 3:58 PM, Johny Kadarisman Kwan <jkr888@gmail.com>wrote:

I’m attempting to setup FS to failover from gw1, gw2, and gw3 subsequently. AND if any gateway response with NO_ANSWER or ALLOTED_TIMEOUT, then the next attempt should be stop. Using “fail_on_single_reject” var, I tried following script :

<extension name="public_extensions">

<condition field="destination_number" expression="^1234$">

<action application="sleep" data="2000"/>

<action application="answer"/>

<action application="bridge" data="{ignore_early_media=true,fail_on_single_reject=NO_ANSWER, ALLOTTED_TIMEOUT}[leg_timeout=20}]sofia/gateway/gw1/7321231234|[leg_timeout=20]sofia/gateway/gw2/7321231234|[leg_timeout=20]sofia/gateway/gw3/7321231234}"/>

<action application="hangup"/>

</condition>

</extension>

Bridge app still continue attempting call to each gw1, gw2, and gw3 when ALLOTED_TIMEOUT response. From searching lists, above dialplan should work out fine. Did I misses any steps?

Btw, tried above on FreeSWITCH Version 1.5.6b+git~20131010T172322Z~1cd6d44b06 (git 1cd6d44 2013-10-10 17:23:22Z) windows built.

Thanks,
