Voice Over IP: SpectraLink

SpectraLink is the only company to offer a complete portfolio of wireless telephone systems for the workplace and is dedicated to meeting the communication needs of mobile workers. SpectraLink has developed products that integrate with all enterprise telephony technologies, from the most widely used traditional PBX systems to the leading-edge IP-based convergence platforms. We provide systems with dedicated wireless infrastructure for minimal administration and high reliability, and systems that utilize standards-based wireless LAN infrastructure to serve mobile voice and data requirements. NetLink from Spectralink is the wireless LAN convergence system for legacy PBX systems and enterprise voice over IP (VoIP) networks. The system is highly flexible and scalable to provide wireless VoIP in almost any customer situation. The NetLink system consists of up to three of the following components: NetLink Telephony Gateway, NetLink SVP Server, and NetLink Wireless Telephone. A NetLink Telephony Gateway is required only for connections to a legacy PBX. Interfaces to current and future IP PBXs do not require a gateway. The NetLink Telephony Gateway is connected to analog or digital station ports within the facility's telephone switch. When a call destined for a NetLink Wireless Telephone is received, the NetLink Telephony Gateway converts the PBX call to Internet Protocol (IP) packets and sends them out over the customer's 802.11b wireless LAN. The NetLink Wireless Telephone then receives the voice packets and assembles the conversation while maintaining excellent voice quality. Voice quality is the main function of the NetLink SVP Server. SpectraLink Voice Priority (SVP) ensures that voice packets have priority over data packets on the wireless network.
