'SiriKit INStartCallIntent not working on iPad

I've implemented Siri support in my app that supports video and VoIP calls. I am able to use Siri with my app on iPhone, but on iPad, Siri responds with "Sorry, I can't help you with that on iPad". I've found articles about Siri not working, and gone through troubleshooting with no success. I've enabled iPad in my intents extension's deployment info, and I haven't seen anything in the APIs about iPad support specifically. This is my first time working with Siri, but I'm finding it to be a black box that doesn't give us much to go on when it doesn't work as expected. Am I missing something, or is this just one of Siri's quirks?
