The Cisco WIP310 Wireless-G IP Phone enables high-quality voice over IP (VoIP) service through a Wireless-G network. The Cisco WIP310 operates in the 2.4-GHz band and supports 802.11b/g and the latest VoIP Session Initiation Protocol (SIP). The large, full-color high-resolution display features an intuitive user interface that enables users to easily and quickly configure the handset with network access using Wi-Fi Protected Setup (WPS). WPS is a fast, highly secure way of connecting the Cisco WIP310 IP phone with any standards-based Wireless-G broadband router. Just press the WPS button and your connection will automatically be configured and secured with a custom service set identifier (SSID) using powerful Wi-Fi Protected Access (WPA) encryption. Within seconds you have successfully set up a highly secure connection. The Cisco WIP310 uses the same trusted and proven provisioning capabilities presently being used to deploy other popular Cisco voice products for small and medium-sized businesses on a massive scale. Customers purchasing VoIP service from a service provider and using the Cisco WIP310 can be quickly provisioned over a Wi-Fi connection, receiving their configuration profile securely right to the handset via a Trivial File Transfer Protocol (TFTP), HTTP, or HTTPS download. The included telephone base accentuates the modern design of the handset and provides hands-free convenience when using the built-in speakerphone. The Cisco WIP310 supports many features such as caller ID, call forwarding, call transfer, and three-way conferencing and can store 200 records in its phone book
