Hi guys, I’ll try to send an Sip Info message on PJSIP_INV_STATE_CONFIRMED state during enstablished dialog. On on_call_state(…) pjsua Callback I have introduced the following code but I obtained a crash: void PjCallback::on_call_state(pjsua_call_id call_id, pjsip_event *e) { pj_status_t status; //Obtain detail information about the specified call pjsua_call_info ci; status = pjsua_call_get_info(call_id, &ci); //Obtain detail information about the specified call pjsip_tx_data tdata; //Pointer to tdata pjsip_tx_data *pTdata; //take the address of tdata pTdata = &tdata; //Pointer to pointer tdata pjsip_tx_data **ppTdata; //take the address of pTdata using address of operator & ppTdata = &pTdata; //Get incoming message buffer pjsip_rx_data *rdata; rdata = e->body.tsx_state.src.rdata; //Get pjsip_dialog pjsip_dialog *dlg; dlg = pjsip_rdata_get_dlg(rdata); //Get endpoint pjsip_endpoint *endpt = pjsua_get_pjsip_endpt(); //Define standard xml to send in Info Sip body message pj_str_t xmlString = pj_str("<note> <to>Tove</to> <from>Jani</from> <heading>Reminder</heading> <body>Don't forget me this weekend!</body> </note>"); pj_str_t typeMessage = pj_str("text"); pj_str_t subtypeMessage = pj_str("xml"); pj_pool_t *poolTest; poolTest = pjsua_pool_create("infoMessage", 1000, 1000); pjsip_msg_body *createMessageBody; char dup[1500]; switch(ci.state) { case PJSIP_INV_STATE_CONFIRMED: //Body Sip Info message createMessageBody = pjsip_msg_body_create(poolTest, &typeMessage, &subtypeMessage, &xmlString); pjsip_print_text_body(createMessageBody, dup, sizeof(dup)); //Create dialog request status = pjsip_dlg_create_request(dlg, &pjsip_info_method, -1, ppTdata); if (status == PJ_SUCCESS) { //Send request (send Info message status = pjsip_dlg_send_request(dlg, pTdata, -1, NULL); } break; default: ; } } I get a crash when I call pjsip_msg_body_create function. Where is the problem? Thanks in advice. Best Regards Ll |
