INStartCallIntentHandling How do I ask user to select one of Multiple Numbers

I'm trying to use SiriKit INStartCallIntentHandling to place telephone calls. I can write my handler to "home in" on the correct contact to dial BUT how should I get SIRI to ask the user which number he/she wants to dial?

I see with Siri and the native phone App Siri asks "which number for" ... Mobile, Home, Work etc BUT I cannot see how to do that with my VoIP App.

Anybody got any tips on this?
