Cisco CP-6901-K9 Unified Single-Line IP Desk Phone (SCCP/SIP Dual Protocol), Trimline Low-Profile Design, No LCD Display, 10/100 Fast Ethernet, IEEE 802.3af Class 1 PoE Powered, Supports Two Concurrent Calls with Call Waiting, Dedicated Hold / Redial / Call Waiting Fixed Keys, Supports Hookswitch-Based Transfer & Conference, Eco-Friendly Recyclable Plastic Chassis, Charcoal Standard Chassis with Optional Slimline/Standard Handset Variants, Desktop or Wall Mountable, Ideal for Hotel Guest Rooms, Building Lobbies, Elevators, Hallways, Public Restrooms and Light Occasional Voice Use Environments

Full Commercial Overview

The Cisco CP-6901-K9 belongs to Cisco Unified IP Phone 6900 Series, a cost-optimized entry-level single-line VoIP endpoint designed for low-traffic, occasional voice communication scenarios rather than daily office staff useCisco. It supports dual call control protocols: proprietary SCCP (Skinny Client Control Protocol) for Cisco Unified Communications Manager (CUCM) / CUCM Business Edition / UCME, and open SIP for third-party SIP PBX platformsCisco.

Distinctive hardware features separate it from higher-tier Cisco desk phones: it hasno LCD screen, a compact slim trimline footprint, minimal fixed function keys, and ultra-low power consumption via Class 1 PoE. Each unit can handle up to two simultaneous incoming calls with native call waiting support. Transfer and three-way conference functions are implemented through traditional analog phone hookswitch operations instead of dedicated hardware keys, reducing overall hardware cost and complexityCisco.

Customization options include two chassis color choices (charcoal black base model CP-6901-K9; arctic white CP-6901-W-K9), plus two interchangeable handset styles: standard curved handset and slimline compact handset (CP-6901-CL-K9 variant). The device uses recycled and recyclable plastic materials to meet environmental sustainability standards, with low idle power draw for energy efficiencyCisco.

All configuration, provisioning and firmware upgrades are managed via TFTP auto-provisioning, embedded web administration interface and CUCM centralized management tools. It supports secure voice transport with TLS signaling encryption and SRTP media encryption for enterprise-grade communications security.

Hardware & Physical Design Architecture

1. Compact Low-Profile Chassis & Mounting Options

• Form factor: Trimline flat compact desktop body with foldable adjustable foot stand for comfortable desk placement; the foot stand can be fully removed for direct wall mounting without extra wall mount kit accessories, with pre-drilled mounting holes on rear panelCisco.
• Chassis material: Reground recyclable ABS plastic; base CP-6901-K9 ships in matte charcoal black finish.
• Handset options: Standard ergonomic handset included by default; slimline lightweight handset available as separate PID CP-6901-CL-K9.

2. Key Layout & Control Hardware (No LCD Screen)

The CP-6901 omits a display panel entirely to cut cost and simplify deployment, relying on LED status indicators and tactile fixed function keys:

1. Single tricolor illuminated line key: Visual state indication (solid green = idle line; solid red = active/held call; flashing red = incoming ringing call)
2. Three dedicated fixed hardware keys for one-touch operation: Hold, Redial, Call Waiting
3. Standard 12-key numeric dial pad (0–9, *, #) with rounded tactile keys for easy operation
4. Hookswitch sensor integrated into handset cradle to enable Transfer and Conference functions without dedicated keys
5. Single red Message Waiting Indicator (MWI) LED on top of chassis to alert users of unheard voicemail messages

3. Audio Subsystem & Supported Voice Codecs

• Integrated analog handset with built-in receiver and microphone; internal speaker for ringtone audio only (no full-duplex speakerphone functionality)

Core Telephony Feature Set

All calling and configuration functions are provisioned via CUCM / SIP PBX auto-provisioning templates; basic operations are triggered via physical keys or hookswitch actions:

1. Single-Line Multi-Call Handling Supports up to two concurrent active calls with native call waiting service; call hold via dedicated Hold key. Call transfer and three-way audio conference functions are activated by lifting the handset hookswitch (traditional analog phone operation workflow).
2. Caller ID & Personalization Features Incoming Caller ID name/number delivered via audio ringtone cadence and MWI LED alert (no screen display for visual ID text); adjustable ringtone volume and ringer tone selection; customizable line ring alert patterns.
3. Basic Utility Calling Functions One-touch redial via dedicated Redial key; call waiting toggle via fixed Call Waiting key; shared line appearance monitoring support for multi-user shared guest room / lobby lines.
4. Voicemail MWI Integration Native Message Waiting Indicator (MWI) notification via SIP/SCCP SUBSCRIBE/NOTIFY messaging; solid red LED illumination on chassis top to notify users of unheard voicemail messages.
5. Supported Security Call Features Anonymous incoming call rejection; outbound caller ID blocking via server-side configuration; encrypted SIP signaling (TLS) and encrypted voice media streams (SRTP) for enterprise secure communications deployments.

Security & Remote Device Management Capabilities

1. End-to-End Encrypted Communications TLS transport layer encryption for SCCP/SIP call control signaling; SRTP AES encrypted RTP voice media streams to prevent call audio interception on shared LAN networks.
2. Multi-Tier Access Permissions Separate administrator and end-user access privilege levels protected by unique authentication passwords; password-locked factory reset function to block unauthorized wiping of device configuration and line registration data.
3. Centralized Auto-Provisioning & Firmware Upgrades Unattended remote bulk firmware upgrades via TFTP/HTTP/HTTPS secure auto-provisioning servers, compatible with CUCM and third-party SIP PBX platforms. Embedded web-based administration interface for local device configuration and status monitoring.
