Hello all, I read docs and I can see that there's echo cancellation support in PJSUA. It seems also that on Mac OS, CoreAudio should do the trick. --- build info --- PJSIP 2.x version, compiled libraries on Mac OS Lion 10.7.5 (darwin kernel 11.4.2) embedded in a simple XCode 4.5.2 project (with MAC SDK 10.8 - deployment target 10.7 - 64 bit). --- end build info --- If I init PJSUA without media configuration, i.e: pjsua_init(&cfg, &log_cfg, NULL); and I use integrated Mac speakers+mic (no hearphones) I hear a lot of echo! So I tried to enable echo cancellation in code with: // other code ... pjsua_media_config_default(&media_cfg); media_cfg.ec_options = PJMEDIA_ECHO_DEFAULT; media_cfg.ec_tail_len = 1200; ... pjsua_init(&cfg, &log_cfg, &media_cfg); // other code but nothing changes... What I have to do to enable it?
