Register and listen on the specified port

The following example shows you how to register to sip server and set local port 5060 as listener port. User contact address is sip:Bob@192.168.2.2:5060 . Method OnReceiveRequest shows you that user will accept any request/call from the server or another sip client.

C# example

using System;
using System.Net;
using Independentsoft.Sip;

namespace Sample
{
    class Program
    {
        private static Logger logger;
        private static SipClient client;

        public static void Main(string[] args)
        {
            client = new SipClient("sipdomain.com", "Bob", "password");

            //create logger
            logger = new Logger();
            logger.WriteLog += new WriteLogEventHandler(OnWriteLog);
            client.Logger = logger;

            client.ReceiveRequest += new ReceiveRequestEventHandler(OnReceiveRequest);
            client.ReceiveResponse += new ReceiveResponseEventHandler(OnReceiveResponse);

            //IPHostEntry localhost = Dns.Resolve("mycomputer"); 
            //client.LocalIPEndPoint = new IPEndPoint(localhost.AddressList[0],5060);

            System.Net.IPAddress localAddress = System.Net.IPAddress.Parse("192.168.2.2");
            client.LocalIPEndPoint = new System.Net.IPEndPoint(localAddress, 5060);

            client.Connect();

            client.Register("sip:sipdomain.com", "sip:Bob@mydomain.com", "sip:Bob@" + client.LocalIPEndPoint.ToString());

            Console.WriteLine("Press ENTER to exit.");
            Console.Read();
            client.Disconnect();
        }

        private static void OnReceiveRequest(object sender, RequestEventArgs e)
        {
            //accept any request from server or another sip user agent
            client.AcceptRequest(e.Request);
        }

        private static void OnReceiveResponse(object sender, ResponseEventArgs e)
        {
        }

        private static void OnWriteLog(object sender, WriteLogEventArgs e)
        {
            Console.Write(e.Log);
        }
    }
}

VB example

    Private logger As Logger
    Private client As SipClient

    Public Sub Main(ByVal args() As String)
        client = New SipClient("sipdomain.com", "Bob", "password")

        'create logger
        logger = New Logger
        AddHandler logger.WriteLog, AddressOf OnWriteLog
        client.Logger = logger

        AddHandler client.ReceiveRequest, AddressOf OnReceiveRequest
        AddHandler client.ReceiveResponse, AddressOf OnReceiveResponse

        'IPHostEntry localhost = Dns.Resolve("mycomputer"); 
        'client.LocalIPEndPoint = new IPEndPoint(localhost.AddressList[0],5060);

        Dim localAddress As System.Net.IPAddress = System.Net.IPAddress.Parse("192.168.2.2")
        client.LocalIPEndPoint = New System.Net.IPEndPoint(localAddress, 5060)

        client.Connect()

        client.Register("sip:sipdomain.com", "sip:Bob@mydomain.com", "sip:Bob@" + client.LocalIPEndPoint.ToString())

        Console.WriteLine("Press ENTER to exit.")
        Console.Read()
        client.Disconnect()
    End Sub

    Private Sub OnReceiveRequest(ByVal sender As Object, ByVal e As RequestEventArgs)
        'accept any request from server or another sip user agent
        client.AcceptRequest(e.Request)
    End Sub

    Private Sub OnReceiveResponse(ByVal sender As Object, ByVal e As ResponseEventArgs)
    End Sub

    Private Sub OnWriteLog(ByVal sender As Object, ByVal e As WriteLogEventArgs)
        Console.Write(e.Log)
    End Sub
