Viking VoIP Ceiling Speaker with Talk-Back and Bluetooth 40TB-IP, PoE, SIP and Multicast
Page it. Talk back. One ceiling speaker.
A PoE-powered IP ceiling speaker that plays pages and multicast audio, and lets people in the room talk back over SIP. It runs on a single network connection.

A one-way speaker can't hear the room.
Paging only works if the room can respond. A talk-back speaker turns an announcement into a two-way conversation, including in noisy spaces.
Paging and talk-back in one
The 40TB-IP works as a SIP endpoint or a multicast group member, so it fits both calling and paging setups.
Two-way talk-back
Takes two-way calls as a SIP endpoint, and VOX switching removes the need for Push to Talk mode.

multicast paging groups
Supported by a single speaker.
Multicast paging
Plays audio from multicast, supports up to 10 multicast paging groups and includes paging prioritization.
Automatic Noise Canceling
The ANC feature is built for operation in noisy environments.
Optional strobe and remote
Add an optional SL-2 strobe light in blue, green, red or amber, or use an optional BTR-3 wireless remote to activate calls or adjust volume.
