Phone Overview

The Cisco Unified IP Phone 6901 and 6911 provides voice communication over an Internet Protocol (IP)
network. The Cisco Unified IP Phone functions much like a digital business phone, allowing you to place and
receive phone calls. The Cisco Unified IP Phones in this guide have the following attributes:
• Cisco Unified IP Phone 6901 supports basic features such as hold, redial, transfer, and conference.
• Cisco Unified IP Phone 6911 supports advanced features such as mute, hold, transfer, conference, speed
A Cisco Unified IP Phone, like other network devices, must be configured and managed. These phones encode
G.711a, G.711mu, G.729a, G.729ab, and iLBC codecs, and decode G.711a, G.711mu, G.729, G.729ab, and
iLBC codecs. These phones encode and decode the codecs in similar manner.
Caution
Using a cell, mobile, or GSM phone, or two-way radio in close proximity to a Cisco Unified IP Phone might
cause interference. For more information, refer to the manufacturer's documentation of the interfering device.
For more information, see the Cisco Unified IP Phone 6901 and 6911 User Guide for Cisco Unified
Communications Manager (SCCP and SIP).

    Cisco Unified IP Phones. The Cisco Unified IP Phone 6901 and 6911 use the Phone security profile, which defines whether the device is nonsecure, authenticated, or encrypted. For information on applying the security profile to the phone, see the Cisco Unified Communications Manager Security Guide.
  • Page 17 Troubleshooting and Maintenance Supported Security Features The following table provides an overview of the security features that the Cisco Unified IP Phone 6901 and 6911 support. For more information about these features and about Cisco Unified Communications Manager and Cisco Unified IP Phone security, see the Cisco Unified Communications Manager Security Guide.

  • Page 19 Feature Description Signaling encryption Ensures that all SCCP and SIP signaling messages sent between the phone and the Cisco Unified Communications Manager server are encrypted. Certificate Authority Proxy Function (CAPF) Implements parts of the certificate generation procedure that are too processing-intensive for the phone, and interacts with the phone for key generation and certificate installation.

  • Page 22 Cisco Unified IP Phones provide an EAPOL pass-through mechanism. This mechanism allows a workstation attached to the Cisco Unified IP Phone to pass EAPOL messages to the 802.1X authenticator at the LAN switch. The pass-through mechanism ensures that the IP phone does not act as the LAN switch to authenticate a data endpoint before accessing the network.
  • Page 23 • Cisco Catalyst Switch (or other third-party switch): The switch must support 802.1X, so it can act as the authenticator and pass the messages between the phone and the authentication server. After the exchange completes, the switch grants or denies the phone access to the network.
