Hi all, Anybody know if there is more params to adjust? I am building an user agent on symbian platform using VAS/AMR codec, it works but the voice quality is poor. In order to fine tuning I have change the following things 1) Default codec , I have changed the definition for AMR?s codec_desc in passthrough codec.c. the default mode and frame per packet have been adjusted (I just change them same as nokia's own PoC client). 2) Media_cfg. Using default configuration. default param is most suitable for VAS/AMR passthrough codec, right? Still the quality is uncomparable with Nokia's own client (NOKIA PTT client). The delay is longer (Nokia's is 1 second around while mine is 2 seconds around) and jitter is obvious. The network is GRPS/EDGE. Is there any more params I can adjust to improve voice quality? -------------- next part -------------- An HTML attachment was scrubbed...
