Hi, I'v found that there will is going to be a implementation of APS for PJSIP symbian soon. >From a mail of Nanang : http://lists.pjsip.org/pipermail/pjsip_lists.pjsip.org/2008-July/003522.html I have some queries regarding this... Is it possible to implement APS only in sound device part(symbian_sound.cpp) of the PJSIP Media Flow. From my limited understanding I'v found that if we could get linear PCM from the APS then we might need to update only the symbian_sound.cpp for the implementation (using the pjsip's existing codecs not from APS). But in the latest APS api PCM is not supported and codec part is not independent from sound device part of APS, then what would be the possible way to implement APS. Do we need to make major changes in the media flow part of PJSIP to implement APS? Sorry for my bad english and long sentences.
