Default Behavior
Phone Service is a Win32 service. In Windows 11 it starts only if the user, an application or another service starts it. When the Phone Service is started, it logs on as NT Authority\LocalService and running in a shared process of svchost.exe. If Phone Service fails to start, the failure details will be recorded into Event Log. Then Windows 11 should boot up and notify the user about the PhoneSvc service startup failure.
Dependencies
Phone Service cannot be started, if the Remote Procedure Call (RPC) service won't start.
