Cisco 6861 SIP Phone with Multiplatform Firmware - Refurbished

Engineered specifically for cloud-hosted PBX frameworks and open SIP infrastructures, the Cisco IP Phone 6861 running Multiplatform Phone Firmware delivers reliable, business-grade communications. By pairing a clear 3.2-inch white-backlit greyscale display (320 x 120 pixels) with integrated dual-band Wi-Fi connectivity, a 10/100 Ethernet port, and professional wideband audio, this desk phone provides exceptional productivity for modern office spaces and home offices.

*Please Note - This unit arrives preloaded with Multiplatform (3PCC) firmware, designating it exclusively for open SIP call control networks like Cisco Webex Calling, BroadWorks, Asterisk, and Metaswitch rather than proprietary Cisco enterprise systems.

Clear 3.2-Inch Greyscale Display Interface

Designed to streamline everyday desk-based workflows, the Cisco 6861 features a practical 3.2-inch white-backlit greyscale LCD display (320 × 120 pixels). This high-contrast visual workspace provides sharp legibility for checking caller ID information, reviewing local call histories, and navigating text-based XML applications, ensuring staff can manage daily call volumes without visual clutter.

Integrated Dual-Band Wi-Fi & Flexible Deployment

Offering exceptional deployment versatility, the 6861 includes built-in dual-band wireless LAN connectivity supporting 2.4GHz and 5GHz networks. This allows businesses and home-working operators to connect the phone securely to local Wi-Fi networks using WEP, WPA-PSK, WPA2-PSK, or EAP protocols, eliminating physical cabling constraints while maintaining a stable, high-quality voice connection.

Optimised for Open-Standard Hosted Environments

Built to accommodate businesses operating outside traditional walled-garden ecosystems, this model marries legendary Cisco hardware durability with open-standard SIP flexibility. It integrates smoothly into modern cloud communication setups, granting administrators the freedom to pair the terminal with market-leading hosted platforms including Cisco Webex Calling, Webex Calling Carrier, BroadWorks, Asterisk, and Metaswitch.

Streamlined Call Control & Multi-Line Versatility

Designed to minimise office friction and speed up daily administrative tasks, the phone provides an extensive toolkit of calling features supporting up to 4 distinct SIP line registrations. Users can effortlessly execute call transfers, place calls on hold, retrieve parked lines, initiate local three-way conferences, and manage group pickups. Furthermore, four dedicated programmable line and feature keys alongside four context-sensitive soft keys allow operators to configure speed dials or monitor specific extensions instantly.

Professional Audio Clarity & Headset Support

Clear acoustic performance is essential for commercial productivity. The hardware supports wideband audio across the handset and full-duplex speakerphone, ensuring every conversation sounds vibrant and distortion-free. Additionally, the phone features an analogue wideband-capable RJ-9 headset port with support for electronic hookswitch (EHS) adapters via its auxiliary port, giving users greater freedom with compatible wireless and corded headsets.

Multi-Layered Enterprise Security Infrastructure

Protecting sensitive corporate networks from unauthorised access is a top priority. This terminal employs rigorous security standards, including IEEE 802.1X authentication protocols, encrypted configuration files, password login protections, and Secure Real-Time Transport Protocol (SRTP) encryption with AES-128 or AES-256 for live media streams. Mass rollouts are equally streamlined via automated TFTP, HTTP, or HTTPS server provisioning.
