WebRTC enables dialing out and you need to be attached to an extension to use this capability. You can configure this in the Online Web Portal for Production (https://service.ringcentral.com/) and Sandbox (https://service.devtest.ringcentral.com/) accounts. You can find more information on the Digital Lines and their configuration in the following RingCentral Knowledge Base article topics:
- Digital Line Overview (KB 5862) - http://success.ringcentral.com/articles/en_US/RC_Knowledge_Article/5862 RingCentral DigitalLine Overview
- Adding a Digital Line (KB 3136). - The application should have an allocated Digital Line. A limited number of Digital Lines are free with each sandbox account and can be configured with the free RingCentral for Desktop softphone. - http://success.ringcentral.com/articles/RC_Knowledge_Article/5-10-Adding-Phones-to-other-extensions-via-Web
- Reassigning an Existing Digital Line (KB 3748) - http://success.ringcentral.com/articles/en_US/RC_Knowledge_Article/How-to-Assign-an-Existing-Digital-Line-to-a-different-extension
These permissions are configured for your app in the RingCentral Developer Portal (https://developers.ringcentral.com/). Fill in the Registration Form (https://goo.gl/sPsrXN) to get access to the WebRTC permissions. Please contact devsupport@ringcentral.com to request these permissions.
