Comprehensive Interoperability and SIP-Based Feature Set
Based on SIP, the Cisco SPA 303 3-Line IP Phone with 2-Port Switch has been tested to help 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.

and Cisco XML applications when interfacing with the Cisco Unified Communications 500 Series in SPCP mode.
