Hi,
I want create a Back to Back User Agent who is transparent for UA that establishing a call.So I need to forward all incoming call to its final destination.I try to use PJSUA, but I didn't find any function doing this, and I try to create it, with this code :
************************************************ ** Code Adding in the end of pjsua_call.c (and definition in .h) ** ************************************************
/* * Forwarding call to the specified URI using the specified account. */PJ_DEF(pj_status_t) pjsua_forward(pjsua_call_id call_id, pjsip_msg *msg){ pjsip_tx_data *tdata; pj_str_t contact; pj_status_t status; pjsua_call_info * info; pjsua_acc_id acc_id; /* Get Info about current call. */ pjsua_call_get_info (call_id, &info); /* Set account id to current account id */ /*acc_id = info -> acc_id;*/
/* Create request. */ status = pjsip_endpt_create_request(pjsua_var.endpt, &pjsip_message_method, NULL, NULL,NULL, NULL, NULL, -1, NULL, &tdata); if (status != PJ_SUCCESS) { pjsua_perror(THIS_FILE, "Unable to create request", status); return status; }
/* If account is locked to specific transport, then set transport to * the request. */ /*if (pjsua_var.acc[acc_id].cfg.transport_id != PJSUA_INVALID_ID) { pjsip_tpselector tp_sel;
pjsua_init_tpselector(pjsua_var.acc[acc_id].cfg.transport_id, &tp_sel); pjsip_tx_data_set_transport(tdata, &tp_sel); }*/ /* Add msg to tdata->msg */ tdata->msg = msg;
/* Add message body */ status = pjsip_msg_body_copy(tdata->pool, tdata->msg->body, msg->body); if (status != PJ_SUCCESS) { pjsua_perror(THIS_FILE, "Unable to create msg body", PJ_ENOMEM); pjsip_tx_data_dec_ref(tdata); return PJ_ENOMEM; }
/* Add route set */ /*pjsua_set_msg_route_set(tdata, &pjsua_var.acc[acc_id].route_set);*/
/* Send request (statefully) */ status = pjsip_endpt_send_request( pjsua_var.endpt, tdata, -1, NULL, NULL); if (status != PJ_SUCCESS) { pjsua_perror(THIS_FILE, "Unable to send request", status); return status; }
return PJ_SUCCESS;}
And I create a Basic PJSUA Application Like this :
************************************************************ ** Basic PJSUA Application to test pjsua_forward in objective of made a B2BUA ** ************************************************************
#include <pjsua-lib/pjsua.h>
#define THIS_FILE __FILE__
/* Init PJSUA. */static pj_status_t app_init(void);
/* Run PJSUA */static pj_status_t app_run(void);
/* Callback called by the library when call's state has changed */static void on_call_state(pjsua_call_id call_id, pjsip_event *e){
pjsua_call_info ci;
PJ_UNUSED_ARG(e);
pjsua_call_get_info(call_id, &ci); PJ_LOG(3,(THIS_FILE, "Call %d state=%.*s", call_id, (int)ci.state_text.slen, ci.state_text.ptr));}
/* Display error and exit application */static void error_exit(const char *title, pj_status_t status){ pjsua_perror(THIS_FILE, title, status); pjsua_destroy(); exit(1);}
/* Callback called by the library upon receiving incoming call */static void on_incoming_call(pjsua_acc_id acc_id, pjsua_call_id call_id, pjsip_rx_data *rdata){
pjsua_call_info ci;
PJ_UNUSED_ARG(acc_id); PJ_UNUSED_ARG(rdata);
pjsua_call_get_info(call_id, &ci);
PJ_LOG(3,(THIS_FILE, "Incoming call from %.*s!!", (int)ci.remote_info.slen, ci.remote_info.ptr));
/* Automatically answer incoming calls with 200/OK */ pjsua_forward(call_id, rdata->msg_info.msg);
}
int main(int argc, char *argv[]){ app_init(); app_run();}
static pj_status_t app_init(void){ pjsua_config ua_cfg; pjsua_logging_config log_cfg; pjsua_media_config media_cfg; pj_status_t status;
// Must create pjsua before anything else! status = pjsua_create(); if (status != PJ_SUCCESS) { pjsua_perror(THIS_FILE, "Error initializing pjsua", status); return status; }
// Initialize configs with default settings. pjsua_config_default(&ua_cfg); pjsua_logging_config_default(&log_cfg); pjsua_media_config_default(&media_cfg);
// At the very least, application would want to override // the call callbacks in pjsua_config: ua_cfg.cb.on_incoming_call = &on_incoming_call; ua_cfg.cb.on_call_state = on_call_state;
// Customize other settings (or initialize them from application specific // configuration file):
// Initialize pjsua status = pjsua_init(&ua_cfg, &log_cfg, &media_cfg); if (status != PJ_SUCCESS) { pjsua_perror(THIS_FILE, "Error initializing pjsua", status); return status; }
/* Add UDP transport. */ { pjsua_transport_config cfg;
pjsua_transport_config_default(&cfg); cfg.port = 5060; status = pjsua_transport_create(PJSIP_TRANSPORT_UDP, &cfg, NULL); if (status != PJ_SUCCESS) error_exit("Error creating transport", status); }}
static pj_status_t app_run(void){ pj_status_t status;
// Start pjsua status = pjsua_start(); if (status != PJ_SUCCESS) { pjsua_destroy(); pjsua_perror(THIS_FILE, "Error starting pjsua", status); return status; }
// Run application loop while (1) { char choice[10]; printf("Running."); fgets(choice, sizeof(choice), stdin); printf("%s", choice); }}
Compiling it's ok, running it's, but when incomming calls arrives I have this error :
******** Error ********After reception of the Invite, I can show it on the console screen, and just after I have this :
b2b: ../src/pjsua-lib/pjsua_acc.c:1347: pjsua_acc_find_for_incoming: Assertion `pjsua_var.acc_cnt!=0' failed.Abandon
To understand my error, I try to log on a file when I arrives in first function I have created, but, I don't arrives to this.I don't understand what's happens !!!
Anyone can helps me ?
I thanks you by advance for your help.
C?dric.
