Some example communication systems include a fixed network equipment (FNE) operable to receive a talk group call from a first radio. The FNE is operable to transmit the talk group call to a second radio. The FNE is operable to receive a request for a high priority call. The communication system includes a gateway operable to transmit an interrupt signaling message through a broadband channel to the first radio. The interrupt signaling message includes instructions to de-key from the talk group call. Some example communication systems include a first radio operable to communicate with a second radio in a talk group call. The communication system includes a gateway operable to receive a request for a high priority call. The gateway is operable to transmit an interrupt signaling message through a broadband channel to the first radio. The interrupt signaling message includes instructions to make a high priority call decision.
