[SR-Users] Some clarifications needed on async_task_route

[Daniel-Constantin Mierla]

Hello,

no actions are executed in the same route block after the line with
async_task_route("NICE_TO_HAVE") -- see the readme of the async module
at the documentation for this function.

If you want to continue executing the actions after pushing a task for
another process, you can try to combine mqueue+rtimer, but in your
example won't work, because the rtimer won't have the current sip
message in order to get the dialog for it.

Cheers,
Daniel
