Designed for modern workplaces, the Cisco 8851 IP Phone delivers enterprise-grade voice quality, seamless mobility, and scalable security in a compact, versatile design. This business-class endpoint blends reliable wired performance with cordless flexibility through Bluetooth, enabling users to pair wireless headsets and mobile devices for a connected, friction-free communications experience. With Cisco Intelligent Proximity, personal mobile devices can be controlled from the desk phone, turning your laptop or smartphone into an extension of your office telephony system. The 8851 is purpose-built for small to large organizations that demand robust collaboration tools, secure provisioning, and simple deployment, while offering wall-mountable versatility to fit any office layout. Whether you’re equipping a single executive desk, a busy workspace, or an entire department, the 8851’s combination of corded reliability and cordless convenience helps teams stay connected, energized, and productive throughout the workday.

  • The 8851 delivers corded reliability with the added versatility of Bluetooth for wireless headsets and mobile device pairing, enabling hands-free calls and easy device switching while maintaining crisp, clear audio quality. This enables users to move from desk to hallway, meeting room, or reception area without interrupting conversations, while still maintaining secure, enterprise-grade telephony controls. The Bluetooth integration supports secure pairing with compatible devices, ensuring seamless integration into your existing UC environment and reducing desk clutter from multiple devices.
  • Five-way conferencing and high-fidelity audio bring teams together quickly and clearly. The phone supports multi-party conferences that empower project teams, sales floors, and remote workers to participate in discussions with confidence. Wideband audio, full-duplex speakerphone, and echo cancellation deliver natural voice quality even in busy environments, helping participants hear every detail and respond promptly. With intelligent conferencing controls integrated into Cisco Unified Communications Manager or compatible SIP platforms, scheduling and joining meetings becomes a streamlined part of your daily workflow.
  • Cisco Intelligent Proximity and mobile telephony integration simplify how you work across devices. This feature allows call control, extension dialing, and call transfer between the desk phone and compatible mobile devices, so you can take or route calls from whichever device is most convenient. Directory access, presence information, and call history can be leveraged from the desk unit, reducing the need to juggle multiple apps and devices. This seamless mobility is particularly valuable for managers, field staff, and teams that rely on real-time collaboration while still requiring a stable, on-desk telephony experience.
  • Security, scalability, and enterprise readiness define the 8851’s lifecycle in large deployments. It supports secure provisioning, TLS for signaling, and SRTP for media streams, helping protect sensitive communications. The phone is designed to work with Cisco Unified Communications Manager and other SIP-based deployments, with centralized management and firmware updates to minimize downtime and maintenance. Its robust hardware and software architecture are built to handle the demands of busy offices, long product lifecycles, and the reliability expectations of corporate IT teams.
  • Flexible deployment, ergonomic design, and space-saving versatility round out the package. The 8851 is suitable for wall mounting or desktop use, giving you the flexibility to optimize workspace layouts and minimize clutter. It supports Power over Ethernet for straightforward cabling and can operate with an optional power supply in environments without PoE. A clear, color display presents call status, directories, and quick access to frequently used features, while a compact footprint ensures it fits neatly on crowded desks, reception counters, or cubicle walls. The durable, commercial-grade construction is designed for sustained daily use in support desks, executive offices, call centers, and shared workspaces.

They are using different/cheaper shredded foam then they were 1 year ago
Color: Memory Pillow, Size: Standard, Color: Memory Pillow, Size: Standard
The shredded foam used last year was really nice and soft and even firm to a point where your head is supported perfectly while you sleep. now the 2 extra pillows I received this weekend have completely different shredded foam which seems to be cheaper. Also when you unzip the pillow cover and get to the part where you can unzip the other cover where the foam is no longer is there. so they are using cheaper shredded foam and a cheaper cover to where the foam is and you can no longer unzip the second cover to see the foam. but I can easily tell that they are using different and cheaper foam which isn't true memory foam. their new blend is too fluffy and the pillows are floppy and too soft. the old ones i bought 1 year ago are heavy pillows that are true memory foam which your head molds into perfectly and are amazing. these new ones they are making aren't worth it. In one picture you can see the cover with different colored cheap foam and the other picture with the green and white thick premium quality shredded memory foam. The other pictures show how the old ones are thick and firm and moldable for you head and the other 2 are floppy because they use cheaper shredded foam. They need to use the shredded foam they used last year! it was really good! Now they are not true memory foam pillows anymore due to changing from premium shredded foam to cheap shredded foam.
