Peter,
here is a code snippet showing how to read the a=sendonly or a=inactive attributes from the SDP of a PJSIP SIP msg.
pjmedia_sdp_session *offer;
pjmedia_sdp_media *media;
pjmedia_sdp_attr *attr = NULL
status = pjmedia_sdp_parse(pSipCallLeg->m_pool, (char*)sipMsg->body->data, sipMsg->body->len, &offer);
if (status == PJ_SUCCESS) {
for (i=0; i < (int)offer->media_count; ++i) {
media = offer->media[i];
if (pjmedia_sdp_media_find_attr2(media, "sendonly", NULL) || pjmedia_sdp_media_find_attr2(media, "inactive", NULL))
...
}
}
}
