Siri avoids VoIP/shortcut for calls on iOS in favor of using Phone app
iOS 26.3. The goal is to use Siri to initate a call through a VoIP app, not the phone app.
Siri is enabled.
A shortcut has been created using the call command provided by the VoIP app in question.
In the iOS app settings for the VoIP app, the default calling app has been set to the VoIP app.
Siri ignores "Siri, call [Name]" or "Siri, call [name] per [name of VoIP app]" in favor of launching the phone app.
How can Siri be persuaded to use the shortcut?
