Product Overview

The Cisco Unified IP Phone 6911 is a single-line endpoint delivering affordable access to Cisco voice communication services. It is an ideal solution for light communication requirements. Examples include classrooms, manufacturing floors, or employees in cubicles or teleworking from home.

The Cisco Unified IP Phone 6911 supports two incoming calls with a single-line endpoint. A full-duplex speakerphone is included in the design, which provides a more productive, flexible, and easier-to-use endpoint experience. Integrated IEEE 10/100 Ethernet switch ports support connection to a co-located PC while reducing cabling infrastructure and administration costs.

The Cisco Unified IP Phone 6911 includes fixed keys for hold, transfer, conference, redial, and voicemail, making the phone simple and easy-to-use. In addition, a programmable feature key is supported for quick access to advanced communication services. Tri-color LED illuminates on the line key to provide quick call-state indication at a glance.

The Cisco Unified IP Phone 6911 offers personalization, with the choice of two colors (charcoal and arctic white) and two handset style options (slimline and standard).

The Cisco Unified IP Phone 6911 is also eco-friendly, taking advantage of reground and recyclable plastics to deliver a more earth-responsible solution.

Features and Benefits

Table 1 lists features and benefits of the Cisco Unified IP Phone 6911.

Table 1. Features and Benefits of Cisco Unified IP Phone 6901




Industrial design

The phone offers an easy-to-use and intuitive arrangement of lines, keys, and calls.
Hold, Transfer, Conference, Voice Mail Access, and Redial on fixed hard keys provide a traditional telephony-like user experience.


Choice of two colors: Arctic White or Charcoal. Handsets are available internationally as slimline or standard. You can mix and match them in the work environment to better meet employee preferences.

Desk and wall mountable

A two-position footstand makes it easy to view and use the buttons and keys.
The phone can be wall-mounted with wall-mounting holes located on its rear housing.


You can include your logo on Cisco Unified IP Phone 6900 Series endpoints. Cisco has approved third-party vendors to produce the labels.


An internal 2-port Cisco Ethernet switch allows for a direct connection to an IEEE 10/100BASE-T Ethernet network through an RJ-45 interface with single LAN connectivity for both the phone and a co-located PC. The system administrator can designate separate VLANs (802.1Q) for the PC and phone, providing improved security and reliability of voice and data traffic.

The following audio-compression codecs are supported: encode G.711a, G.711u, G.729a, G.729ab and iLBC, decode G.711a, G.711u, G.729, G.729a, G.729ab and iLBC.

Voice quality

Comfort-noise generation and voice-activity-detection (VAD) programming is supported on a system basis.

Full-duplex speakerphone

You can place and receive calls through the back-lit speaker button.


The phone offers mute and un-mute functions through the back-lit Mute key.
