Cisco IP Phone
The Cisco IP Phone 8841 integrates high-fidelity voice communications with a professional hardware interface for enterprise-grade environments. This model features a 5-inch high-resolution widescreen VGA backlit color display. It supports five programmable line keys for managing multiple directory numbers. Additionally, the internal hardware architecture utilizes a dual-port 10/100/1000BASE-T Ethernet switch. This ensures high-speed network pass-through for co-located PC deployments. Therefore, network engineers can maintain simplified cabling infrastructures while providing high bandwidth to the desktop.
