The CyberData SiP-enabled V2 Ceiling 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 CAT5 cable connection. The speaker is compatible with most SiP-based IP PBX. In a non SiP environment, the speaker is capable of broadcasting audio through multicast. Its small footprint and low height allows the speaker to be discreetly mounted almost anywhere.

The VoIP Ceiling Speaker supports two SIP extensions. One extension can be assigned to a page group for auto answer paging. The second extension can be assigned to a “First-to-Answer” ring group with IP phones. An audio ring file is activated when the second SIP extension of the ceiling speaker is dialed. If any of the IP phones in the ring group is answered (or if the caller hangs up), the Ceiling Speaker stops ringing.
