Are you using the RingCentral SDK for c-sharp? If not, open your project and install the RingCentral SDK via NuGet (search for RingCentral Client 3.0.0 package).

After adding the SDK to your project, you can use it as shown below:

using RingCentral; 

const string RC_CLIENTID = "your app client id";
const string RC_CLIENTSECRET = "your app client secret;
const string RC_SERVER = "";

const string RC_USERNAME = "username";
const string RC_PASSWORD = "password";
const string RC_EXTENSION = "extension number"; 

RestClient rc = null;
SubscriptionService subscription = null;
        protected void Page_Load(object sender, EventArgs args)
            if (rc == null)
                rc = new RestClient(RC_CLIENTID, RC_CLIENTSECRET, false);
                RegisterAsyncTask(new PageAsyncTask(RingCentralAuthenticationAsync));

        private async Task RingCentralAuthenticationAsync()
            await rc.Authorize(RC_USERNAME, RC_EXTENSION, RC_PASSWORD);
            if (rc.token.access_token.Length > 0)
                RegisterAsyncTask(new PageAsyncTask(subscribeForNotification));

        private async Task subscribeForNotification()
            subscription = rc.Restapi().Subscription().New();
            subscription.NotificationEvent += (sender, args) =>

                var message = args.message;


            subscription.StatusEvent += (sender, args) =>

            await subscription.Register();

Check out other notification type. Particularly the "Presence" would give you better telephony status.

Hope this helps!
