Core Design and Regional Compatibility

The ​​CP-6871-3PW-UK-K9=​​ is a ​​Cisco IP Phone 6800 Series​​ model tailored for UK-based deployments. It combines ​​three programmable line keys​​ with ​​PoE+ (802.3at)​​ support, making it suitable for high-demand environments like contact centers or shared office spaces. Unlike generic VoIP phones, its ​​UK-specific power adapter​​ and ​​BS 1363 plug​​ ensure compliance with local electrical standards, eliminating the need for external converters.

Technical Specifications and Performance

• ​​Display​​: ​​5-inch grayscale LCD​​ with adjustable contrast for low-light conditions.
• ​​Audio Codecs​​: Supports ​​G.711, G.729​​, and ​​Opus​​ for balanced bandwidth usage and clarity.
• ​​Power Redundancy​​: ​​Dual power inputs​​ (PoE+ and AC) for uninterrupted operation during outages.
• ​​Security​​: ​​802.1X authentication​​ and ​​SRTP encryption​​ to safeguard voice traffic.

Addressing Deployment Challenges

​​Q: Is this phone compatible with non-Cisco collaboration platforms?​​
No. The CP-6871-3PW-UK-K9= requires ​​Cisco Unified Communications Manager (CUCM)​​ or ​​Webex Calling​​ for full functionality, ensuring end-to-end QoS and security.

​​Q: Can it handle multi-site deployments?​​
Yes. Its ​​built-in Gigabit Ethernet switch​​ allows daisy-chaining to other devices (e.g., PCs) without separate cabling, ideal for space-constrained desks.

Where to Procure Reliable Units

For organizations prioritizing compliance and warranty coverage, “CP-6871-3PW-UK-K9=” is available through itmall.sale, which offers ​​Cisco-verified refurbished units​​ with lifetime technical support.

Practical Perspective

Having deployed these phones in UK financial sectors, I’ve seen their ​​dual power inputs​​ prevent downtime during grid fluctuations—a frequent issue in older buildings. However, the grayscale display can frustrate users accustomed to color interfaces. For teams prioritizing reliability over flashy features, the CP-6871-3PW-UK-K9= delivers unmatched stability in Cisco-centric environments.
