[Freeswitch-users] Qualify a gateway and interact with it before using it..

I want to do this with event socket... I'm just not sure how. - outbound call starting - Validate that a gateway is up - Perform a requred out-of-band operation (an application action probably) on the gateway and wait for it to complete. - Route call to that gateway If the gateway is not up, I'd repeat for secondary and tertiary gateways. Any recipe thoughts? Thanks, -Gerry
