The AtlasIED IPX Series IP-8SM indoor wall / ceiling mount IP speakers with talkback leverage the VoIP Communication solution to extend tele-presence with enhanced audio for those environments where network-wide communication is desired and that require large speakers with high output to overcome high ambient noise areas or large spaces. AtlasIED IP-8SM registers as a communication endpoint directly within InformaCast, and SA-Announce Advanced Notification applications, supporting audio broadcast to enhance physical security while improving day-to-day communications through advanced alerting, bell schedules, pre-recorded, scheduled announcements, & intercom, while leveraging the WAN/LAN Network Architecture. When used within a Cisco Environment, these same IP speakers from AtlasIED can join Cisco’s Unified Survivable Remote Site Telephony (SRST) as a supported device within SRST endpoint Architecture. Cisco’s SRST provides remote location call-processing redundancy when access to the centralized Cisco Unified Communications Manager is interrupted because of a WAN outage. The ability of LAN communication between any combination of phones and speakers is particularly critical during an emergency (which may be the actual cause of the WAN outage).
