A bit more information - I found the corresponding code in
nua_session.c:
------------------------
static void signal_call_state_change():
if (oa_recv) {
soa_get_remote_sdp(nh->nh_soa, &remote_sdp, &remote_sdp_str, 0);
offer_recv = strcasecmp(oa_recv, "offer") == 0;
answer_recv = strcasecmp(oa_recv, "answer") == 0;
}
------------------------
This function doesn't check if remote_sdp... is non-null...
Is it a bug?
