The generation method is that each flow component corresponds to a function of the lua script file, the name of the function is the id of the component, and the content of the function is different according to the functions of the flow components. The next function, the value of the to attribute in the xml file of this flow component information, is called in the last line of each function. The following takes the starting component, the playback component and the DTMF component as an example.

And the default configuration of the task is a stop state, after the task is started, if the task is a timing task, the timing cron expression information is written into a quartz framework, and the quartz framework carries out timing triggering according to the timing expression.
The method mainly comprises the steps of customizing a timed calling task in a service scene needing automatic calling, and mainly setting information such as task timing time, an outbound number, an executed IVR flow and the like.

In order to keep flexibility and configurability, a called number (a main outbound number) and a corresponding IVR flow are associated through configuration, and when the calling time arrives, a command to be executed is spelled out according to the called number and the lua name of the corresponding flow and is sent to a freeswitch soft calling platform. The command structure is as follows:
originate sofia/external/186xxxxxxxx@yyyy&lua(example_lua_location.lua)example_params
