Hi, i have successfully compiled the pjsip(V1.6) with APS support and have been testing the symbian_ua_gui on my nokia E66 with my asterisk server . But it seems that the calls are always made in g711 . codec. I have tried to force the g729 in my config_site_sample.h header file in the following manner: #ifdef PJ_CONFIG_NOKIA_APS_DIRECT /* MUST use switchboard rather than the conference bridge */ #define PJMEDIA_CONF_USE_SWITCH_BOARD 1 /* Enable APS sound device backend and disable MDA & VAS */ #define PJMEDIA_AUDIO_DEV_HAS_SYMB_MDA 0 #define PJMEDIA_AUDIO_DEV_HAS_SYMB_APS 1 #define PJMEDIA_AUDIO_DEV_HAS_SYMB_VAS 0 /* Enable passthrough codec framework */ #define PJMEDIA_HAS_PASSTHROUGH_CODECS 1 /* And selectively enable which codecs are supported by the handset */ #define PJMEDIA_HAS_PASSTHROUGH_CODEC_PCMU 0 #define PJMEDIA_HAS_PASSTHROUGH_CODEC_PCMA 0 #define PJMEDIA_HAS_PASSTHROUGH_CODEC_AMR 0 #define PJMEDIA_HAS_PASSTHROUGH_CODEC_G729 1 #define PJMEDIA_HAS_PASSTHROUGH_CODEC_ILBC 0 #endif as you can see i have disabled all the passthrough codecs except g729. but still the g711 happens . do i need to do something else for that? i would like to contribute to an wiki on how to enable g729 on symbian pjsip -- Regards Shrouk Khan (Khan) System Administrator / Telecommunication System Developer Office: +354 4400807 (Reykjavik) +44 2031370800 (London) Mobile: +66 875049439 (Bangkok) -------------- next part -------------- An HTML attachment was scrubbed...
