About the Cisco CP-3905= IP phone / endpoint
The Cisco CP-3905= SIP IP Phone delivers essential voice communication through a compact desktop endpoint designed for organizations requiring straightforward telephony without advanced display features. This single-line device supports wideband HD audio and full-duplex wideband speakerphone capability, ensuring clear voice quality across all call types. Built on SIP protocol architecture, the CP-3905= integrates seamlessly with Cisco Unified Communications Manager (UCM) and Cisco Webex Calling, providing flexible deployment options for enterprise voice infrastructure. The phone features two integrated 10/100BASE-T Ethernet ports—one for LAN uplink and one for PC pass-through—allowing efficient network connectivity while reducing cable clutter on the desktop.
IT procurement teams and network engineers standardizing Cisco voice endpoints across mid-sized to large deployments typically choose the CP-3905= for branch offices, common areas, and cost-sensitive environments where rich display functionality is unnecessary. The device operates across a standard temperature range of 0°C to 40°C and meets CE, FCC, and UL regulatory compliance standards, making it suitable for global installations. Power flexibility is built in: the phone supports IEEE 802.3af Power over Ethernet (PoE) with optional external power supply availability, eliminating the need for dedicated power infrastructure in many installations. A full set of fixed feature buttons—including Hold, Transfer, Conference, Redial, Volume control, Mute, and Speakerphone—provides intuitive one-touch operation, while wall-mount bracket support enables flexible placement in diverse office layouts.
