The NetVision® Phone from Symbol Technologies adds voice- over-IP (VoIP) communications to Symbol’s Wi-Fi™ certified Spectrum24® 802.11b direct sequence wireless LAN installations, allowing simultaneous voice and data support on the same wireless backbone. Employing VoIP technology based on the ITU standard H.323, the NetVision Phone converts analog voice into compressed digital packets that are sent via TCP/IP protocol over standard data networks.
The IEEE 802.11b-compliant NetVision Phone interoperates with many Wi-Fi certified wireless LANs. Broad support of VoIP solutions from major telephony vendors allows PBX integration of the NetVision Phone via a gateway for internal and external voice communication.
