From https://www.bluetooth.com/specifications/gatt/services/: Phone Alert Status Service it seems that it is up to the connected client (Android) to write to the Alert Status characteristic (Ringer State, Vibrator State, Display Alert State) on the server (whatever device you're envisioning).  There is no mention of what can these Alert States represents, so they can represent an incoming phone call if you want it to. 

Maybe Android has an implementation of this service already, I do not know. If it does not then you need to create an app that listens for whatever event that indicates an incoming call and write to the Alert Status characteristic of your device.
