The CyberData InformaCast Enabled Speaker with Talk-Back is a Power-over-Ethernet (PoE 802.3af/802.3at) and Voice-over-IP (VoIP) public address indoor speaker designed for use with Singlewire's InformaCast paging and emergency notification software. Easily connecting into existing local area networks with a single Ethernet cable connection, its small footprint and minimal depth allows it to be discreetly mounted almost anywhere with multiple mounting options available.
The Talk-Back feature, when enabled, provides full-duplex two-way conversations in indoor settings such as classrooms, offices, medical facilities and clinics. When used with the Remote Call Button, calls to a predetermined extension can be initiated from the room with the speaker. Alternatively, a call can be placed to the speaker to initiate either a page or two-way conversation. This feature also allows for speaker health check.

IP multicast is a technique for one-to-many communication over a local IP network. IGMP multicast is sent via UDP packets from a multicast server to a multicast receiver. This stream scales to a larger receiver population by not requiring prior knowledge of who or how many receivers there are. Multicast uses network infrastructure efficiently by requiring the source to send a packet only once, even if it needs to be delivered to many receivers. The network replicates the packet in order to reach multiple receivers only when necessary.
Multicast is a great alternative to SIP registration as it does not require that the recipient of the stream to register as an extension on an IP-PBX server.
CyberData products support both regular IGMP multicast as well as proprietary Polycom Group Paging.
