VoIP Circuit

The CyberData SIP-enabled Talk-Back Speaker is a Power-over-Ethernet (PoE 802.3af) and Voice-over-IP (VoIP) public address two-way 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 discretely mounted almost anywhere.
