[Freeswitch-users] Bridge app and SIP 503

[Bill W.]

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!
