Alarming notification radio

Attached is a pdf brochure for a device that I would like to ask IA about.
It is a pdf that represents the hardware we use in our current system. A PLC triggers a relay that is wired to the 8 different channels to broadcast an alarm event over our ‘radios’…
What I would like to ask of the forum is what hardware that anybody is using to do something similar.
What I would like to achieve is to find a device or interface component that I can script to in ignition much like the VoIP setup. In a nutshell I am looking for some device that I can configure Ignition to broadcast all the alerts across a 2 way radio repeater system or digital radio system of sorts…
I hope someone can understand what I mean here and respond back to the forum with some information…
