Hi All
How Callback in J2ME can be done? Any nice idea regarding this topic will be highly appreciated.

Hi Javed,

you cannot directly pass functions as arguments within J2me, so one simple approach would be to define an interface (let's say: ICallback) with one method to be called back.

I think this explains it
From Talkonaut FAQ

Java version of Talkonaut utilizes "callback" technique to make voice calls. This means, when it is necessary, our system (GTalk2VoIP gateway) calls back to your mobile phone, then calls to your recipient, after that it merges two voice calls in one.

So they are not really using Java for the call (or audio recording).

I think the idea is that if the calls are in both ends made locally, the call is cheaper if you use talkonaut in between, than if you would pay for the long distance calls.
