Hello Chen-Che,

You can rather insert a "delay" before sending the INVITE out, so you
give a chance the terminal to register.

You can simulate the delay by sending the call to an inexisting
destination with a let's say 2 seconds timeout - in failure route you
can do re-send to the real destination. This is to avoid using sleep()
function which blocks your process
