The originate API does not work that way. The &app(foo) won't be executed
unless the originate is successful. If you get a 4xx/5xx then the originate
will fail and &app(foo) won't ever get executed. There is no notion of
"execute_on_fail" since a failed call means there is no channel/session to
send through the dialplan or through an application.

Depending on exactly what you're doing you probably need to be using "bgapi
originate ..." and then checking the BACKGROUND_JOB event to see what
happened. Alternatively you could be listening/watching for CDRs and then
acting upon them. Alternatively using mod_xml_cdr is an easy way to receive
notification of failed calls. The channel variable
"proto_specific_hangup_cause" will have the "SIP:4xx" value, and you can
react to it accordingly.
