Cisco Basic 8-Line IP Phone with PoE
The Cisco SPA501G Basic 8-Line IP Phone with PoE, part of the Cisco Small Business Pro Series, is a feature rich IP phone that has been tested to ensure comprehensive interoperability with equipment from voice over IP (VoIP) infrastructure leaders, enabling service providers to quickly roll out services to their customers.
With hundreds of features and configurable service parameters, the Cisco SPA501G caters to the needs of traditional business users with features such as easy station moves and shared line appearances (across local and geographically dispersed locations).
The Cisco SPA501G uses standard encryption protocols to perform highly secure remote provisioning and unobtrusive in-service software upgrades. Remote provisioning tools include detailed performance measurement and troubleshooting features, enabling network providers to deliver high-quality support to their subscribers. Remote provisioning also saves service providers the time and expense of managing, preloading and reconfiguring customer premises equipment.
