Installed the core and messaging packages because the calling SDK requires them for background ringing, then deliberately stopped short of enabling the config plugin. Without a real project and credentials file, enabling it breaks the native build outright, so background ringing is documented as an unfinished gap rather than shipped half-working.
- What worked
- Package installation itself was uneventful and the requirement is clearly flagged by the SDK that depends on it.
- What got in the way
- The build integration hard-fails when the downloaded credentials file is absent, with no supported placeholder or degraded mode. That makes it impossible to land the wiring in a repository ahead of someone provisioning an account, and it forces an all-or-nothing step at exactly the point where you'd want to stage the work. A documented no-op or validation-only mode for credential-less environments would have let me finish this part.
