Abstract: A device, system and method for emergency audio transmission is provided. A server receives, over a broadband network, a request to make an emergency audio transmission to a talk group. The request is received from a first push-to-talk (PTT) device communicatively connected with the talk group over a narrow band network at which a second PTT device of the talk group has floor control. In response to granting the request, the server receives, from the first PTT device, an audio transmission over the broadband network, and transmits the audio transmission to the talk group via the broadband network.
