Anonymous calling is a feature on the AT&T API Marketplace https://apimarket.att.com (APIM) where you don’t need a real APIM user in originating side of the call.
As an example use case, you have a web application with a browser app, and on the website you want to add a button that browsing customers can initiate a WebRTC call (with or without video), which can be routed to your application’s IVR number so that your representatives can talk with the customer.
To achieve this flow, there are two important points:
- The target number that is called when anonymous call initiated should be configured under APIM
projectof your app. You can navigate toAnonymous Destinationstab inAPIM custome portaland add your authorized numbers. - This functionality requires an
access_tokenacquired for aproject(viaprivate project keyandsecret). This implies that your app must have a server-side component that can get authenticated. Note that browser apps cannot store secrets securily so that would be a bad idea to use the browser app for project authentication.
If, for any reason, you need to use a project’s
access_tokento make regular calls instead of anoymous calls, you need to addregular_callintoscopeparameter while getting authenticated.
