Comment 29 for bug 1332306

So looking at the dialog in the spec, it should be a simple snap notification emitted by the telephony stack.

EXCEPT, we don't currently support the button on the right being red. We have a rather rigid hint x-canonical-private-rejection-tint=true, which will ONLY tint the left button red.

So there's a tiny bit of work on the unity8/notification side after all. I'm considering adding a hint like x-canonical-private-rejection-actions=listOfActionIds that gives more flexibility.

But that shouldn't block the telephony folks. Just make a snap notification like normal, without any color for now.
