how to record call in blackberry? - blackberry

Question

I want to create an call recorder application in blackberry. While searching in this forum i have got call-recorder-in-blackberry this link. The code given in the below link is fairly understood.
It might be a silly question to you experts but my question is how to us that piece of code. I mean the MyScreen object will work on UIApplication. But how can i make my module start while starting the device, and run in background waiting for the phone call listener to invoke.
I have used this below code, it records the call but only if the call is on loud speaker mode. Now how can i do the same without putting in loud speaker mode.

Answer 1

Actually direct call recording not possible with blackberry. AFAIK that posted code is call recording when call on speakerphone. That means If mobile have the loud speaker, then put a call to loud speaker and record that voice. And look at this discussion, Call recorder in Blackberry.

Answer 2

It's not possible to record the audio of a phone call (other than with a loud speakerphone) as you are trying to do. This is intentional. You would need another approach off the device to do this. However, I can answer your other questions:
To make your application autostart, you can follow these steps: http://supportforums.blackberry.com/t5/Java-Development/Configure-an-application-to-start-automatically-when-the/ta-p/444748
Also, as this application above doesn't extend from UiApplication, you should check the "run as a system module" box as well, when you follow the directions above. That way it won't appear on the ribbon or as an icon in the list of applications.
