2 Different Emergency Notifications on security phones

[TKMan]

My head of security just asked if the security phones (3 buildings in close proximity with 4 different phones) can have a button that when hit will notify the other phones there is an emergency coming from the one phone so the officers can alert each other with a quick button without dialing 911. This would be similar to the button we already have when someone dials 911 these phones get notified. This being said, is there a way to have 2 emergency notification buttons on the phone and how would the two different number ring two different notification buttons, Can I have one notification button but 2 different alarm ring styles or will this not work altogether? Any help would be appreciated.

I don't think it's possible to have two different notification groups but you should be able to set up a key that will alert everyone with out dialing 911.
The alert is triggered whenever a call is routed through an ARS route that is tagged as an emergency call.
Just set up a route to anything else, could be an extension on another node, and tag it as an emergency call.
That will ring everyone in the emergency groups.
