Few things are really confusing here except the royalty fee that we got a pay for g.729. 1) Why I need to worry about audio subsystem. As in encoder part I should take the 16 bit PCM bitstream and convert that to 10 byte g.729 bits and in decoder part I do the vice versa and let the pjmedia take care of the rest. There should not be anything else needed to be done. Am I right? Also it should work for FP1 and FP2 as like as speex and gsm implemented. Please shed some lights on that. Thanks a lot.

Second, also on S60 it will have to be different between S60 MR/FP1 (Audio Proxy Server) and S60 FP1/FP2 devices (Voip Audio Services API) . Fortunately we are lucky that APS on S60 MR/FP1 it's supported while on FP2 it's deprecated but it works. Third, if you implement it in Software (instead of using APS) you will have to pay royalties for each piece distributed. This guide me to say that the more convenient things to do today is to hook APS directly inside PJMEDIA in order to use *for free *royalty-based codec like G729 and AMR, along with Hardware Acceleration and Battery Saving.
