Nanang, can we write a small web page with the description of how the APS could be integrated inside the PJMEDIA Stack? Mr. Karthik Babu of Cytrion proposed himself for the development of such feature. Imho it should be driven by your design consideration, so it would be nice to have your support about it. This implementation can provide to all pjsip users all the hardware codecs support by S60 platform, including royalty based one like G729 and AMR for *free* .
