Cyberdata VoIP Ceiling Speaker SIP - Open Box
The CyberData SIP-enabled VoIP Speaker is a Power-over-Ethernet (PoE 802.3af) and Voice-over-IP (VoIP) public address loudspeaker that easily connects into existing local area networks with a single cable connection. The speaker is compatible with most SIP-based IP PBX servers that comply with the SIP RFC 3261. In a non-SIP environment, the speaker is capable of broadcasting audio played on a multicast addresses and port numbers. The speaker is powered via a standard Ethernet Cat 5 cable - no external power supply is needed. Its small footprint and low height allows the speaker to be discretely mounted almost anywhere.
