Overview

VoIP Phone 7841 with Multiplatform Phone 

 

Cisco 7841 is a Gigabit VoIP phone that supports four SIP registrations. Perfect for everyday users, Cisco 7841 combines the reliability of Cisco's engineering with the style and functionality of the office phone. Gigabit Ethernet means you'll have future-proof bandwidth. The phone is a Class 1 PoE device, so you're able to power it through the network cable. Cisco IP Phone 7841 has a bright, backlit display that provides a simple, intuitive interface for operating the phone. With wideband audio from the hearing aid compatible handset and the full-duplex speakerphone, 7841 also gives you the option to use a headset using the dedicated RJ9 port. Cisco includes enterprise-class networking features, as you'd expect: 802.1x authentication, HTTPS provisioning, TLS and SRTP security, and much more.
