The ask is to make the RingCentral embedded dialer integration deep link to the device's native default browser as opposed to the embedded browsers within Teams. This can be helpful if a customer uses an older embedded version of Chrome and Electron that are no longer secure. By proxy, RingCentral have to use these during the user authentication process. This information can be found in the user agent information with MS Teams Developer options turned on. Microsoft would need to update its core Teams SDK framework to resolve this on the MS side.
