java-based VoIP clients (not dialers) for cell phones
 

Are there generic java-based VoIP clients (not dialers) which will work on Motorola 3G or CDMA EVDO "dumb" phones (such as, for example, Motorola MOTOKRZR K1m)?

Ideally, I am looking for one which supports G729 codec.

I know there is java-based miniFring. And I am looking for the latest installation '*.jar' file for miniFring. Although I am not sure if it will work on Motorola.

Will greatly appreciate any pointers.

Just in case: I am not talking about WM-based smartphones.

G729 is a licensed codec.
So it will probably not be present on any softphone that is free.
