我正在尝试为使用PJSIP作为客户端的ios开发一个SIP呼叫应用程序。我有在云上运行的Kamailio SIP服务器。我无法从我的pjsip客户端拨打音频/视频电话。但是，如果我尝试使用其他第三方应用程序，则可以通过200 OK接听电话，在这种情况下，视频和音频可以正常工作。我正在服务器中记录每个INVITE请求。因此，当我尝试从pjsip客户端发出呼叫时，该呼叫未记录在那里，这意味着它从未到达服务器。但是，如果我尝试其他应用，则会正确记录INVITE请求。
我尝试过的代码如下。这有什么问题吗？
pj_str_t uri = pj_str("sip:901@<MY_IP>:<MY_PORT>");
AppDelegate *appDelegate = (AppDelegate *) [[UIApplication sharedApplication] delegate];
pjsua_call_id p_call_id;
pjsua_call_setting opt;
pjsua_call_setting_default(&opt);
opt.vid_cnt = 1;
opt.aud_cnt = 1;
pjsua_msg_data msg_data;
pjsua_msg_data_init(&msg_data);
pj_status_t status = pjsua_call_make_call(appDelegate.accountId , &uri, 0, NULL, &msg_data, &p_call_id);
if(status == PJ_SUCCESS){
NSLog(@"call made successfully from %d with callID %d",appDelegate.accountId,p_call_id);
if(pjsua_call_is_active(p_call_id)) {
NSLog(@"call is active");
}
}else {
NSLog(@"call made failed");
}
帐户已正确注册，但无法调用任何SIP URI。
