hello all I have special request. I want create call where RTP stream will be sent only one way from caller to callee. Not from callee to caller. 1) exists some "method in SIP message" how can i say collee to not sent RTP stream? Exists something like user data in SIP message? If yes how can i set it? 2) how can i disable RTP stream on collee side? (some API) ..respectively on UA side.I found callback on_stream_created() it is good place? :) thanks

look at the sdp attributes a=sendonly, rcvonly sendrcv http://www.ietf.org/rfc/rfc3264.txt Cheers On Apr 13, 2010, at 10:25 AM, Peter Lukac wrote: > hello all > I have special request.

pjsua_msg_data msg_data;

pjsua_msg_data_init( &msg_data );

pj_str_t hname = pj_str("application/sdp");
pj_str_t hvalue = pj_str("a=sendonly");

msg_data.content_type  = hname;
msg_data.msg_body  = hvalue;

hello again How can i add/modify DPS protocol in SIP message when i creating call? in pjsua_call_make_call method is parameter msg_data.. pj_status_t pjsua_call_make_call ( pjsua_acc_id acc_id, const pj_str_t * dst_uri, unsigned options, void * user_data, const pjsua_msg_data * msg_data, pjsua_call_id * p_call_id ) and i suppose this parameter i have to adjust. But how? when i try: pjsua_msg_data msg_data; pjsua_msg_data_init( &msg_data ); pj_str_t hname = pj_str("application/sdp"); pj_str_t hvalue = pj_str("a=sendonly"); msg_data.content_type = hname; msg_data.msg_body = hvalue; pjsua_call_make_call( acc_id, &pj_uri, 0, NULL, &msg_data, &call_id); in SIP message is still: "a=sendrecv" struct "pjsua_msg_data" have another member "hdr_list" of type "pjsip_hdr" Do i have to adjust this member too?..if yes how? thanks

Hi Peter, On pjsua level, this may be easily done using this trick: 1. normal make call, pjsua_call_make_call() 2. once the call gets confirmed, put the call on-hold, pjsua_call_set_hold(), call hold will put 'sendonly' direction attribute in the sdp.

hi thanks for reply.. this trick is little hack :) and i preffer clean sollutions...it is posible with struct "pjsua_msg_data"? or some callback? or some another way? ( use pjsua API is not necessary but welcome :) ) I want control rtp stream all directions (sendonly,recvonly and sendrecv). thanks > Hi Peter, > > On pjsua level, this may be easily done using this trick: > 1. normal make call, pjsua_call_make_call() > 2. once the call gets confirmed, put the call on-hold, > pjsua_call_set_hold(), call hold will put 'sendonly' direction > attribute in the sdp. > > BR, > nanang > > On Mon, Apr 26, 2010 at 7:23 PM, Peter Lukac <p.lukac@emtest.sk> wrote: > > hello again > > > > How can i add/modify DPS protocol in SIP message when i creating call? > > > > in pjsua_call_make_call method is parameter msg_data.. > > > > > > pj_status_t pjsua_call_make_call (pjsua_acc_id acc_id, > > const pj_str_t * dst_uri, > > unsigned options, > > void * user_data, > > const pjsua_msg_data * msg_data, > > pjsua_call_id * p_call_id > > ) > > and i suppose this parameter i have to adjust.

hi I found point where sdp message is creating.. is it in endpoint.c source file and method "pjmedia_endpt_create_sdp" here is code which add "sendrecv" attribute to SDP message: /* Add sendrecv attribute. */ attr = PJ_POOL_ZALLOC_T(pool, pjmedia_sdp_attr); attr->name = STR_SENDRECV; m->attr[m->attr_count++] = attr; as you see attribute "sendrecv" is still added. No condition if add "sendonly", recvonly" or "sendrecv" attribute should be added :( Maybe exist some callback which can overwrite? But i can't found anything... ..maybe call pjsua_call_set_hold() will be only solution :) On Tuesday 27 April 2010 01:32:50 pm Peter Lukac wrote: > hi > > thanks for reply.. this trick is little hack :) and i preffer clean > sollutions...it is posible with struct "pjsua_msg_data"? or some callback? > or some another way?
