question

Hi Zeeshan,

You would need to Configure the Softphone to Login in the Sandbox Environment. Please refer to this link under the section "Configure Softphone for Sandbox" :
https://developer.ringcentral.com/library/tutorials/test-account.html

You would need to create a config.ini and paste the following :

HttpRegServer = "http://agentconnect.devtest.ringcentral.com";
PlatformServer = "https://platform.devtest.ringcentral.com"   

Make sure to place this file in the "App Folder" of the RingCentral For SoftPone application :

Windows :  Cntrl+F1 
Mac : Fn+Command+F1

Please make sure to select UK as the region in Softphone when you Login. If you are still unable to login you could create a case at " devsupport@ringcentral.com"

Got it thanks

If you're on a Mac, I have written this BASH utility which provides you the ability to quickly toggle between production and sandbox mode for your SoftPhone:

Switching between environments can now be done within the softphone UI.

This is described in the Getting Started Guide's "Your Softphone" section:

• https://developer.ringcentral.com/library/getting-started.html

From the softphone signin screen use the following key combination to bring up the environment toggle:

• Windows: Cntrl+F2
• Mac: Fn+Command+F2
