We have been able to handle incoming calls by making use of the RingCentral Webphone library (https://github.com/ringcentral/ringcentral-web-phone). However, this approach makes use of WebRTC via the browser and therefore when the page is reloaded the active connection/call you are in is lost. We would like a more sturdy and robust integration and are looking into alternative approaches. That is why I would like to know if it is possible to directly control the RingCentral softphone or (physical)desk-phone by using a specific SDK or API. This would give the user a better integration. Does such an SDK or API currently exist? Is this a possible solution or is there another alternative?
