The VoIP Outdoor Intercom Station from AtlasIED is an indoor/outdoor vandalproof, weather-resistant VoIP intercom station with a call-in button. It provides signaling and talkback in environments that are susceptible to damage from abuse, moisture, corrosion, dust, vibration, and extreme temperature. The IPS-VOI registers as a communication endpoint directly to a SIP based communications system to provide signaling and talkback in areas such as guard gates, banks, and distribution centers while leveraging WAN/LAN network architecture. When used within a Cisco Environment, the station can join Cisco's Unified Survivable Remote Site Telephony (SRST) as a supported device within SRST endpoint architecture.
