Save Call on Java Mobile / Phone to mp3 or any Audio format / file

I want to Save Call on Java Mobile / Phone to mp3 or any Audio format / file . How should I go ahead with.

I am quite well versed with Core Java. I found apps supporting above mentioned functionality in symbian Phones only but NOT in Java phones whose MIDP version is 2.1 and above.

Thanks for your Idea ( obviously practical one's ! ) or sharing some links relevant to this or some sort of pseudo-code in java for this.

I want solution for Java Phones with MIDP 2.1 & above.Please don't recommend symbian or other such things.

Solution

I think nobody developed a call recorder in Java platform. All that you can do to record is to call divert to a land line which is connected to computer which can record calls.

Something for your reference (these can't provide you with Java phone call recording but can guide you , why it can't be with Java & S60 would be better(&only) option. )

Java Voice Recorder ported from E398

Need to develop a call recorder

and if change your mind from Java to Symbain then here's a code which you can have a look at.

Try Symbian!
