this is what I'm using to enable Echo Cancellation on the ios (pjsip 2.1)
// we have an user setting to play with it/
pjsua_media_config_default(&(_app_config.media_cfg));
_app_config.media_cfg.clock_rate = 16000;
_app_config.media_cfg.snd_clock_rate = 16000;
if (![[NSUserDefaults standardUserDefaults] boolForKey:@"enableEC"]) {
_app_config.media_cfg.ec_tail_len = 0;
}
