Hi, you can use the code bellow. The last argument is the priority, when its zero the codec i disables (I think...). pj_str_t tmp; pjsua_codec_set_priority(pj_cstr(&tmp, "pcmu"), 240); pjsua_codec_set_priority(pj_cstr(&tmp, "pcma"), 100); pjsua_codec_set_priority(pj_cstr(&tmp, "speex/8000"), 0); pjsua_codec_set_priority(pj_cstr(&tmp, "ilbc"), 0); pjsua_codec_set_priority(pj_cstr(&tmp, "speex/16000"), 0); pjsua_codec_set_priority(pj_cstr(&tmp, "speex/32000"), 0); pjsua_codec_set_priority(pj_cstr(&tmp, "gsm"), 0); Thiago Paiva Flores > > Hi everybody. > > Please tell me which codec is defualt codec in > PJSUA.
