Get options - Advanced method

The GetOptions method sends OPTIONS request to query a client or server about its capabilities (which methods supports, what formats accepts, ...). Another way to send OPTIONS request is shown in example below.

C# example

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

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

            client.Connect();
            client.Register("sip:sipdomain.com", "sip:Bob@mydomain.com", "sip:Bob@mydomain.com");

            Options options = new Options();
            options.Uri = "sip:Alice@mydomain.com";
            options.From = new ContactInfo("Bob", "sip:Bob@mydomain.com");
            options.To = new ContactInfo("Alice", "sip:Alice@mydomain.com");
            options.Contact = new Contact("Bob", "sip:Bob@mydomain.com");

            RequestResponse optionsRequestResponse = client.SendRequest(options);
            Response response = optionsRequestResponse.Response;

            Console.WriteLine("Accept=" + response.Header[StandardHeader.Accept]);
            Console.WriteLine("Allow=" + response.Header[StandardHeader.Allow]);
            Console.WriteLine("Supported=" + response.Header[StandardHeader.Supported]);
            Console.WriteLine("AcceptLanguage=" + response.Header[StandardHeader.AcceptLanguage]);
            Console.WriteLine("AcceptEncoding=" + response.Header[StandardHeader.AcceptEncoding]);

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

VB example

Imports System
Imports Independentsoft.Sip
Imports Independentsoft.Sip.Methods

Module Module1
    Public Sub Main(ByVal args() As String)

        Dim client As SipClient = New SipClient("sipdomain.com", "Bob", "password")

        client.Connect()
        client.Register("sip:sipdomain.com", "sip:Bob@mydomain.com", "sip:Bob@mydomain.com")

        Dim options As Options = New Options
        options.Uri = "sip:Alice@mydomain.com"
        options.From = New ContactInfo("Bob", "sip:Bob@mydomain.com")
        options.To = New ContactInfo("Alice", "sip:Alice@mydomain.com")
        options.Contact = New Contact("Bob", "sip:Bob@mydomain.com")

        Dim optionsRequestResponse As RequestResponse = client.SendRequest(options)
        Dim response As Response = optionsRequestResponse.Response

        Console.WriteLine("Accept=" + response.Header(StandardHeader.Accept))
        Console.WriteLine("Allow=" + response.Header(StandardHeader.Allow))
        Console.WriteLine("Supported=" + response.Header(StandardHeader.Supported))
        Console.WriteLine("AcceptLanguage=" + response.Header(StandardHeader.AcceptLanguage))
        Console.WriteLine("AcceptEncoding=" + response.Header(StandardHeader.AcceptEncoding))

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

    End Sub
End Module
