CyberData SIP - IP speaker - for PA system

The CyberData SIP speaker is a Power-over-Ethernet (PoE 802.3af/802.3at) and Voice-over-IP (VoIP) public address loudspeaker that easily connects into existing local area networks with a single Cat 5 cable connection. The speaker is compatible with most SIP-based IP PBX. In a non-SIP environment, the speaker is capable of playing audio from a multicast source. Its small footprint and low height allows the speaker to be discreetly mounted almost anywhere.
