Logging into sandbox with softphone

In the old version of ring central you used to be able to download the app and press Ctrl+F2 to log into the sandbox to test making calls with an online device. How do I accomplish that now with the new version of the app?

I am trying to use the


endpoint, and it is telling me I am not providing a valid deviceId.

I am using


to get the device Id, but the device is showing offline because I cannot log into the softphone in the samebox environment.

You can now use the Web app to use with your sandbox account at

Or you still can use the RingCentral soft phone app as before. Look on the right pane of this page, it's available for download under the "DEVELOPER SANDBOX TOOLS" section.

As I mentioned in my question, ctrl+F2 no longer works with the main app, so the information on the right page of the page is not helpful.

The web app did get me in, but the device is still not registering as online. And it will not allow me to save an emergency address, and the Company settings return a 404. How do I get it to show the device as online?

Are you on Windows or Mac OS? It works for me to switch mode

It looks like you are using the old app. I was using the new one from the downloads page.

I downloaded the old one, it does let me switch to the dev environment, but it can't make calls out, or set my emergency address.

It seems at the moment that the emergency address issue is holding me up from making calls or bringing the device online.

Is there a place where I can subscribe to know when the Ring Central development group has solved the issue of sandbox phones not being able to make test calls?

I would like to wire up automated testing for my integration with the call-out api, but cannot do that until this issue has been fixed.
