Help with the RingOut code sample in Getting Started
+3Welcome to the home of the RingCentral developer community, where developers and users come together to ask questions, seek support, and work together to get the most out of RingCentral's unified communication platform.
This article is provided to developers going through the getting started experience accessible from within the [RingCentral Developer Console][1] and needing help specifically with the "Initiate a phone call" code sample.
![4522-screen-shot-2023-07-20-at-104146-am.png][2]
Here are some tips and tricks to help you complete this code sample successfully.
**I am not receiving a phone call**
The code sample is executed in our sandbox environment. Therefore, to receive a phone call you must be logged into our web-based unified application in sandbox. Using the credentials you setting in a previous step of the getting started experience, login to your sandbox at the following URL:
https://app.devtest.ringcentral.com
**I am receiving an error when I run my code sample**
The code sample provided for you is 100% complete and ready to go. You should not need to edit it in any way. However, if you are still receiving an error, check the following.
Make sure you installed the SDK. If the error message relates to a missing library or a file that cannot be found, return to step 2 on the making a simple API call page, and follow the instructions for your preferred programming language to properly install the RingCentral SDK.

Using c#, I followed the instructions for .net 2.1 and Nuget package RingCentral,net 4.1.0
The sample code given by the website will not compile.
The error is on this line of code
restClient.Authorize(JWT_TOKEN).Wait();
Error (active) CS1503 Argument 1: cannot convert from 'string' to 'RingCentral.GetTokenRequest' RingDemo C:\Users\joels\source\repos\RingDemo\RingDemo\Pages\Contact.cshtml.cs 39

Please try this sample code
That worked,
The problem was that I followed the instructions for creating a new Visual Studio project which say to use .NET 2.1 and RingCentral 4.1.0.
I created a new project with .netcore 8 and it works.
Can you update the web page instruction which currently say this
Create a Visual Studio project
- Choose Console Application .Net Core -> App
- Select Target Framework .NET Core 2.1
- Enter project name "Call_Ringout"
- Add NuGet package RingCentral.Net (4.1.0) SDK

It should work with Core 2.1 and above. At least 2.1 is what I am using. I think the new SDK does not like this way of calling asynchronous function.
restClient.Authorize(JWT_TOKEN).Wait();
Function is now Task and called differently.
await restClient.Authorize("RC_USER_JWT");
await call_ringout();
