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.
