One possible solution is <action application="set" data="hangup_after_bridge=true"/> <action application="set" data="sip_ignore_remote_cause=true"/> <action application="bridge" data="..."/> <action application="hangup" data="..."/> Failed calls will hit the hangup and hangup with a different reason to the bleg. That will let you return something other than 503. You could instead run a lua script if you want to add some intelligence to return different responses based on what comes back from the gateway or which gateway it is. A better solution might be to disable it on the balancer before doing fsctl pause. Steve on iPhone On 25 Feb 2011, at 20:11, "Bill W." <freeswitch@aastral.net> wrote:

Hi all,

I'm using a failover bridge string with several gateways.

<action application="bridge" data="sofia/gateway/primary/dialstring|sofia/gateway/secondary/dialstring"/>

One of the gateways responded to a mis-dialed number with a "503 Service Unavailable" instead of a "484 Address Incomplete"

My FreeSWITCH servers are behind a load-balancer, and what is happening is the bridge app is passing that 503 back to the load-balancer which then marks that gateway as down.

I can't remove the 503 detection from the load balancer, because that's how I disable a gateway from within freeswitch (fsctl pause, which sends 503).

Does anyone have any recommendations on how to address this issue?

Thanks!
