And for those wondering:

<extension name="call to 1234">

  <condition field="destination_number" expression="^(1234)$">

    <action application="set" data="orig_dest=$1"/>

    <action application="set" data="bypass_media=true"/>

    <action application="set" data="hangup_afer_bridge=true"/>

    <action application="set" data="transfer_on_fail=PROGRESS_TIMEOUT,USER_BUSY,NORMAL_TEMPORARY_FAILURE"/>

    <action application="bridge" data="{progress_timeout=2}sofia/external/sip:1234@192.168.1.123"/>

  </condition>

</extension>

<extension name="call to 1234">

  <condition field="destination_number" expression="^PROGRESS_TIMEOUT$">

    <action application="log" data="CRIT We can have progress timeouts?"/>

  </condition>

</extension>

See XML on https://freeswitch.org/jira/browse/FS-3193

I fear this isn't documented correctly.

There is no such thing as hangup_on_bridge, and if you wish to try a different gateway if the first one doesn't respond quick enough with progress do this:

<extension name="call to 1234">

  <condition field="destination_number" expression="^1234$">

    <action application="set" data="bypass_media=true"/>

    <action application="set" data="hangup_after_bridge=true"/>

    <action application="bridge" data="{progress_timeout=2}sofia/internal/sip:1234@switch2-asdfa.com"/>

    <action application="bridge" data="{progress_timeout=10}sofia/internal/sip:1234@switch1-asdfa.com"/>

  </condition>

</extension>

There is no reason to do what you were doing in this case.

I can't seem to get transfer_on_fail to work. I'm not sure what I'm doing wrong, it just doesn't transfer to the transfer_on_fail extension. The dialplan is below.

The idea is to set leg_progress_timeout = 3, so that if the device isn't responding to INVITEs, we use transfer_on_fail with the cause PROGRESS_TIMEOUT to send the call somewhere else. But transfer_on_fail never seems to get executed when we test it out. The FS logs show that we're hitting PROGRESS_TIMEOUT when the device doesn't respond to INVITEs, so I'm pretty sure we have the right hangup cause, but it's just not catching transfer_on_fail ...

Here's a small snippet of the logs when leg_progress_timeout expires ...
