I started testing this with the following dialplan:

    <extension name="mikael-nokia+fallback">
      <condition field="destination_number" expression="^503$">
        <action application="set" data="hangup_after_bridge=false"/>
        <action application="set" data="continue_on_fail=true"/>
        <action application="bridge"
data="user/mikael-nokia at fs.voip.domain.com"/>
        <action application="info"/>    
        <action application="set" data="followme_extension=99355151"/>
        <action application="execute_extension"
data="post_call_followme_check"/>
        <action application="hangup"/>
      </condition>
    </extension>

  <extension name="post_call_followme_check">
    <condition field="destination_number"
expression="^post_call_followme_check$"/>
    <condition field="${originate_disposition}"
expression="^MEDIA_TIMEOUT|$${continue_on_fail_causes}$"
break="on-true">
      <action application="log" data="1 Follow me transferring call
because of orig disposition: ${originate_disposition}"/>
      <action application="transfer" data="${followme_extension}"/>
    </condition>
    <condition>
      <action application="log" data="1 Follow me call ended normally
with orig disposition: ${originate_disposition}."/>
      <action application="hangup"/>
    </condition>
  </extension>

${originate_disposition} never has the value of MEDIA_TIMEOUT since the
call was answered, which is absolutely correct, so what I am searching
for now is how to get the actual hangup cause. The info app doesn't show
MEDIA_TIMEOUT anywhere, but my logs show this:

How do I get the "raw" hangup cause first mentioned below?

sofia/internal/sip:mikael-nokia at 10.247.3.253 hanging up, cause:
MEDIA_TIMEOUT
"

As mentioned earlier the origination was in fact a success, but since I
moved out of wi-fi coverage area I got a MEDIA_TIMEOUT which should
trigger a transfer to my cell phone number. :-)
