SPA504G-RF
4 Line IP Phone With Display, PoE and PC Port REMANUFACTURED
Part of the Cisco Small Business Series, the SIP-based Cisco SPA 504G 4-Line IP Phone has been tested to ensure comprehensive interoperability with equipment from voice over IP (VoIP) infrastructure leaders, enabling service providers to quickly roll out competitive, feature-rich services to their customers.
With hundreds of features and configurable service parameters, the Cisco SPA 504G addresses the requirements of traditional business users while building on the advantages of IP telephony. Features such as easy station moves and shared line appearances (across local and geographically dispersed locations) are just some of the many advantages of the SPA 504G.
