Hello,

working one:
http://pastebin.com/ncyxUQj8

nonworking one with 503 service unavailable
http://pastebin.com/w7A689Bu

Here i have two scenarios, first is configured with Provider(1), this call routed and established successfully.
the second is configured with Provider(2), with this one freeswitch sending 503 event before routing the call to Provider(2)

so why 503?
