尝试从PJSIP ios调用时，邀请请求未发出

我正在尝试为ios制作一个SIP呼叫应用程序，我使用PJSIP作为客户端。我在云上运行Kamailio SIP服务器。我无法从pjsip客户端进行音频/视频呼叫。但是如果我尝试使用其他第三方应用程序，我可以用200 OK接听电话，在这种情况下，视频和音频工作正常。我正在服务器上记录每个邀请请求。因此，当我试图从pjsip客户端进行调用时，它没有被记录在那里，这意味着它从未到达服务器。但如果我尝试其他应用程序，邀请请求将被正确记录

我尝试过的代码如下所示。这有什么不对

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

下面是pjsip在XCode中完成的日志

从跟踪来看，sip:901@:肯定不是有效的URI；必须用有效值替换占位符

我知道。因为安全问题，我把它们遮住了。；所以这些痕迹是误导性的！很难说，但我希望请求uri应该类似于sip：901@dns-没有IP和端口的fqdn；然后为传输TCP sip添加修饰URI：901@sipserver.net;传输=tcp并解析IP，如sip：901@10.0.0.2;传输=tcp。你得到了这个方法，我想你从一个通用的URI开始，一个一个地添加更改。你找到解决方案了吗？
