hey all.
I'm using ICE module in pjnath. And now I realy need some suggest from you
since that ICE didn't work well as I expected.
The control flow is about below.
-------------------------------------------------------------------------
pj_stun_config stun_cfg;
create_stun_config(pool,&stun_cfg);
pj_ice_strans *ice_st;
pj_ice_strans_cfg cfg;
pj_ice_strans_cfg_default(&cfg);
cfg.stun_cfg = stun_cfg;
pj_ice_strans_cb cb;
/* Init callback */
pj_bzero(&cb, sizeof(cb));
cb.on_ice_complete = &ice_complete;
cb.on_rx_data = &rx_data;
cfg.stun.server = pj_str("stun.xxx.com");
cfg.stun.port = 3478;
cfg.turn.server = pj_str("55.55.55.55");
cfg.turn.port = 3478;
cfg.turn.conn_type = PJ_TURN_TP_UDP;
cfg.turn.auth_cred.type = PJ_STUN_AUTH_CRED_STATIC ;
cfg.turn.auth_cred.data.static_cred.data_type = PJ_STUN_PASSWD_PLAIN;
cfg.turn.auth_cred.data.static_cred.username = pj_str("san at xxx.com");
cfg.turn.auth_cred.data.static_cred.data = pj_str("123456");
pj_ice_strans_create("ice_strans",&cfg, 3, NULL, &cb,&ice_st);
pj_ice_strans_init_ice(ice_st, PJ_ICE_SESS_ROLE_UNKNOWN, NULL, NULL);
//..........................something else.

and there is the output:

I have some problem with pj_ice_init_ice();
I captured packets using tcpdump, it shows a success binding response from
stun, and a error 401 with turn response,but ICE didn't continue interactive
with turn server(In my opinion, ice_init() should continue send request to
turn server with proper attributes such as nonce, realm,e.g.). ICE also
didn't add mapped address from stun's respnose to a component.
I think there must be a mistake i made. but I have no idea how to do.
Can anyone suggest something for me?
Thanks very much && best regards!
