I'm using CTelephony to make calls. Once I make a call then the call goes through, but I would like to be notified about the status of the call from time-to-time. Like when the call is accepted, ended, put on hold then I should be notified through a callback.
GetLineStatus gives me this info, but I have to call it perodically. What I want it to be notified about it as it happens. Is this possible?
