The CyberData Multicast Microphone is a device that allows the user, while pressing the "Page" button, to broadcast a live or buffered announcements directly to VoIP audio endpoints that support multicast.
This PoE-powered product is perfect for immediate live paging in schools, retail stores and manufacturing environments. In an echo sensitive environment, the delayed page support allows the user to record a message while the page button is depressed. Once the page button is released, the page will be sent.

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.
Go to the Downloads tab, click on the serial number range matching your device and download the firmware compatible with it. V3 Firmware is not backwards compatible. Please contact VoIP Technical Support for assistance before attempting a firmware upgrade on a Pre-V3 device. To load the firmware from your PC, see your Operations Guide.
Please adjust the switch power selection to Power inline static, as opposed to Power inline dynamic. This will allow the device to continuously receive 15.4W of power.
There are known PoE limitations with third party devices on the Cisco Catalyst series switches. This includes the 2500, 3500, and 6500 series switches. It?s important to keep in mind that CyberData devices are considered third party devices and require switch port setting adjustments. Be sure to turn power policing off if it has been enabled on your switch. Power policing is disabled by default. Also, configure your port for no shutdown. Use the following command to configure inline power: power inline static max 15400
Be sure to refer to the Installation Quick Reference Guide for wall mounting or gang box mounting installation options. The intercom must be electrically grounded. This will prevent static electricity from interfering with the intercom operation or damaging the unit.
