how to determine remote user actions during CDMA call

[sapanshah.ce]

Hi all,

I am using different Call.State to determine current active call status. When I call
mPhone.dial(Phone_number);

function, I can hear the ring back tone. But call status changes from
DIALING to ACTIVE. And when remote user accpet the call, there is no change in call status.

How can I know when user has accpted the call / remote user has rejected the call?

Also when I received Call.State.DISCONNECTED, I need to know whether remote user has ended the active call, or remote user has rejected the call request?

I am new to android. Thanks in Advanced for the help.

Regards
Sapan
