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.
