[Freeswitch-users] Send call to different place on busy vs no answer

You can check the originate_disposition variable to get the result of
the bridge, then based on that run the voicemail app or play the
message. It is possible to do this in the dialplan, something like:
<condition field="${originate_disposition}" data="USER_BUSY">
  <action application="say" ..
  <anti-action application="voicemail" ...

but I find any logic even slightly more complex than 'if this do that'
in the XML is unreadable because of having to worry about
require-nested, break and inline and reach for the lua:
if session:ready() then
  originate_disposition = session:getVariable("originate_disposition")
  if originate_disposition == 'USER_BUSY' then
play message
  else if originate_disposition == 'ALLOTTED_TIMEOUT' then
do voicemail
    session:consoleLog("INFO", "unhandled disposition" ..
tostring(originate_disposition) .. "\n")
    .. do something sensible (like voicemail)
