These are all in great condition, and many of them may be new, but since they did not come in their sealed plastic (not sure if they do when they are new), just in case, I am listing them as used. The vast majority of them are in their original box, and come with manual / paperwork, and mounting screws, but not every one has them, so the last ones sold may only include the paging amp. They are all guaranteed to arrive working 100% properly. CYBERDATA AMP VOIP PAGING V2 25W PAGING AMPLIFIER 011061The CyberData V2 SIP-enabled VoIP Paging Amplifier provides an easy method for implementing an IP-based overhead paging system for both new and legacy installations. With up to 25 watts of driving power (802.3at), the Amplifier provides direct drive of a standard Horn speaker and supports a line-out connector for connection to an external amplifier. The interface is compatible with most SIP-based IP PBX servers that comply with the SIP RFC 3261. For non-SIP environments, the Paging Amplifier can be configured to listen to multicast address and port number combinations to form paging zones.Specifications:011061VOIP V2 PAGING AMPLIFIERSIP ENABLEDDUAL SPEED EHERNET 10/100MBPSPOE 802.3AT AND 802.3AF ENABLED
