Register - Advanced method

Here we use Register class and method SendRequest to register to sip server. With Register class developer has possibility to set standard and custom headers for register request. In this example Bob's registration will expire after 1 hour ( 3600 seconds ). Bob wants to accept only requests from user with address sip:alice@mydomain.com, other requests he will reject.

C# example

using System;
using Independentsoft.Sip;
using Independentsoft.Sip.Methods;

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);

            client.Connect();

            Register register = new Register();
            register.Uri = "sip:sipdomain.com";
            register.From = new ContactInfo("Bob", "sip:Bob@mydomain.com");
            register.To = new ContactInfo("Bob", "sip:Bob@mydomain.com");
            register.Header[StandardHeader.Contact] = "sip:Bob@" + client.LocalIPEndPoint.ToString();
            register.Expires = 3600;

            client.SendRequest(register);

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

        private static void OnReceiveRequest(object sender, RequestEventArgs e)
        {
            Request incomingRequest = e.Request;

            if (incomingRequest.From.Address == "sip:alice@mydomain.com")
            {
                client.AcceptRequest(incomingRequest);
            }
            else
            {
                client.RejectRequest(incomingRequest);
            }
        }

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

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

Module Module1
    Private logger As Logger
    Private client As SipClient

    Public Sub Main(ByVal args() As String)

        register.Header(StandardHeader.Contact) = "sip:Bob@" + client.LocalIPEndPoint.ToString()
        register.Expires = 3600

        client.SendRequest(register)

        Console.WriteLine("Press ENTER to exit.")
        Console.Read()
