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 SPA504G.<\/div>\n<p><a name=\"wp9000153\"><\/a><\/p>\n<div class=\"pBodyCMT\">The Cisco SPA504G 4-Line IP phone also supports productivity-enhancing features such as VoiceView Express and Cisco XML applications when used with the Cisco Unified Communications 500 Series in SPCP mode.<\/div>\n<p><a name=\"wp9000154\"><\/a><\/p>\n<p class=\"pSubhead1CMT\">Carrier-Grade Security, Provisioning, and Management<\/p>\n<p><a name=\"wp9000155\"><\/a><\/p>\n<div class=\"pBodyCMT\">The Cisco SPA504G 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.<\/div>\n<p><a name=\"wp9000156\"><\/a><\/p>\n<p
