Fabio, Seems like I am going to start working on this G.729 APS implementation. I did some home work and I believe it shouldn't be a big deal. Is there anybody else working on this issue so that I could co-ordinate with him?

And it has to be written considering that APS on FP2+ is already deprecated and will need to be changed to VAS. Hardware codec will provide royalty-paid codec for free (already licensed on S60 platform) and precious battery saving, but will remove some features like conference calling. It's something that could be estimated in 20-30 man working days depending on the expertise on pjsip platform. Of the player of the discussion is there someone willing to invest such time?
