Hello RingCentral Community,

I hope you're all doing well. I'm currently working on integrating the RingCentral Embeddable Voice SDK into my ASP.NET MVC project to add phone call abilities. While I've managed to successfully embed the SDK into my project and the widget appears as expected, I'm encountering an issue where the call icon does not appear, and I'm unable to initiate calls.

Here are the details of my setup:

- I've included the RingCentral Embeddable Voice SDK using the following script tag in my HTML:

```html

Hi @Ahmed Mahmoud Do you use free developer account to login for test in production environment? From the screenshots, the login user doesn't have full permission for call.
If you just want to test at development, you can use sandbox environment. You need to add appServer in the URI's query:
https://ringcentral.github.io/ringcentral-embeddable-voice/adapter.js?appServer="https://platform.devtest.ringcentral.com"
Then you can use sandbox account that you get from RingCentral developer portal for testing.

And you also need to make sure the WebView is based on Chromium (new edge). Old edge or IE can't have calling feature work well.
