I just verified with the examples/sd-example-incoming-call.py from lp:unity-notifications (you need to "sudo apt-get install python-notify" too) on the GalaxyNexus (using: build saucy-24), that notifications are correctly rendered, if the right parameters were passed. I'm now looking into the phone-app to see what arguments it passes to the notification.
