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

[Kristian Kielhofner]

Try this:

<extension name="9_GW" >
  <condition field="destination_number" expression="^(9\d+)$">
    <action application="set" data="continue_on_fail=true"/>
    <action application="set" data="failure_causes=UNALLOCATED_NUMBER"/>
    <action application="set" data="hangup_after_bridge=true"/>
    <action application="bridge" data="sofia/internal/$1 at 192.168.200.201"/>
    <action application="bridge" data="sofia/internal/$1 at 192.168.200.202"/>
 </condition>
</extension>
