[Linphone-developers] receiver answer detection

[Jinsong Hu]

Hi, There,

  I want to see if we can get this use case to work. when I use linphonec to call the receiver, the receiver may or may not pick up the phone. Currently, linphonec command tool only shows media established when the call goes through. At that time, the receiver may

or may not have actually picked up the phone. What I would like to do is that I will immediately play a sound file if he pick up the phone. If he never pick up the phone, I will keep on ringing until give up.  The purpose of this function is that I want to be able to

deliver a message to the receiver and make sure I indeed delivered it by detecting the receiver have picked up the phone. For a human being as a caller, this is easy. However, if I want to script this using a computer as caller, I would like to know if there is a good solution.

  Do we know if this can be done ? If it can, what do I need to change to make this possible ?
