使用Ozeki SDK进行SIP注册无法正常工作

Question

我正在尝试使用c#构建一个简单的VoIP应用程序,所以我发现这Ozeki SDK是一种简单的方法,但是当我尝试使用SIPAccount来自Ozeki SDK和我的本地的类注册SIP帐户时,IP它总是失败,这就是代码

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using Ozeki.VoIP;
using Ozeki.VoIP.SDK;

namespace SIP_R
{
    class Program
    {
        private static ISoftPhone softphone;   // softphone object
        private static IPhoneLine phoneLine;   // phoneline object

        private static void Main(string[] args)
        {
            // Create a softphone object with RTP port range 5000-10000
            softphone = SoftPhoneFactory.CreateSoftPhone(5000, 10000);

            // SIP account registration data, (supplied by your VoIP service provider)
            var registrationRequired = true;
            var userName = "1000";
            var displayName = "1000";
            var authenticationId = "1000";
            var registerPassword = "1000";
            var domainHost = SoftPhoneFactory.GetLocalIP().ToString();
            var domainPort = 9000;

            var account = new SIPAccount(registrationRequired, displayName, userName, authenticationId, registerPassword, domainHost, domainPort);

            // Send SIP regitration request
            RegisterAccount(account);

            // Prevents the termination of the application
            Console.ReadLine();
        }

        static void RegisterAccount(SIPAccount account)
        {
            try
            {
                phoneLine = softphone.CreatePhoneLine(account);
                phoneLine.RegistrationStateChanged += sipAccount_RegStateChanged;
                softphone.RegisterPhoneLine(phoneLine);
            }
            catch (Exception ex)
            {
                Console.WriteLine("Error during SIP registration: " + ex);
            }
        }

        static void sipAccount_RegStateChanged(object sender, RegistrationStateChangedArgs e)
        {
            if (e.State == RegState.Error || e.State == RegState.NotRegistered)
                Console.WriteLine("Registration failed!");

            if (e.State == RegState.RegistrationSucceeded)
                Console.WriteLine("Registration succeeded - Online!");
        }
    }
}

所以,请提前做任何帮助,以获得任何帮助.

当尝试使用Ozeki SDK和本地IP进行软电话呼叫时,会出错 NatType:UDPBlocked

Answer 1

您是否同时打开了 UDP 和 TCP 端口 5060？（标准 SIP 端口）您可以从您的开发计算机注册普通的 SIP 软电话吗？

从您的错误消息来看，您似乎遇到了防火墙问题，而不是代码问题。

查看您的代码，我会检查您输入的所有端口：5,000 到 10,000。
