Cisco SPA504G is a reliable VoIP phone with both SIP and Cisco’s own SPCP protocol. This phone supports a wide range of call features and functions, including many options to customize the device to your own needs. The dual Ethernet ports on the rear side of the phone support PoE which provides the power to run the device.
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. The Cisco Desk phone can be expanded through available expansion modules (SPA500DS and SPA500S). Or connect a headset to the 2.5 mm jack to increase the ease of use. The built-in speaker is perfect for local 3-way conferencing. Wideband audio offers high-quality speech and sound performance.
