如何知道一个呼叫已经建立？ [英] How to know if a call has been established?

问题描述

嗯，我做了一个计划，打电话到任意数量的我的联系人列表中，它就像一个魅力。问题是，我想知道，如果连接已estabilished（其他人并拿起电话），我有没有关于如何做到这一点的想法。

Well, I did a program to make a call to any number of my contact list and it works like a charm. The problem is that I would like to know if the connection has been estabilished (the other person has picked up the phone), and I have not any idea about how to do it.

有没有类似的东西，可以提醒我，当连接已经estabilished中断？

Is there something like an interrupt that can alert me when the connection has been estabilished?
