I have to develop an application where I need to call a number and leave a message to that number.
and I have two cases like:
Case I: when the callee answers the call, I will leave him the message.
Case II: the callee will not lift the call and it goes to the automated answering machine and here I need to leave him the message when we hear a beep sound.
I was able to do the Case I. When it comes to Case II I am unable to find the way to find a solution or a dialplan for it.
Can any one please suggest me in finding the solution for this.
Thanks in advance,
