I have several questions to ask for help

Press the button when coming, and the screen will display "XXX tone connection"

as follows

then start to calculate the call time

now I want him to stay in the XXX connection until my server response connection is successful.

what should I do if I don"t know what to do?

the second problem is that if you want to make phone calls from the native call log, you have to put id in the
function of the native phone and write it here in CXCallUpdate

but where should it exist if it is the buyer"s license?
