Federal Signal has integrated our IP Intelligent Systems product line to enable SIP (session initiation protocol). Our IP devices can now be utilized in hazardous locations, light industrial, or community warning settings and function without the need for on-premise control software. The IP speakers can be utilized for LIVE PA VOIP, as well as using DTMF commands on SIP capable phones to push pre-recorded voice messages. Every IP product has its own web page allowing for easy setup. The IP products come standard with over 300 different standard tone and voice recordings to choose from.
