[Freeswitch-users] FS -route to next GW if the first GW full

[Stephen Wilde]

By default, when a "condition" block is completed (in your case after the
first bridge) then execution of dialplan breaks and the inbound call is
dropped.
You can change this default behaviour with: break="never" in the first
conditional block.
In this case also the second conditional block is always executed.
So your first conditional block will be:

<condition field="destination_number" expression="^(9\d+)$" break="never">
 ....
