Cisco Unified IP Phone

Phone Overview

The Cisco Unified IP Phone 6921, 6941, 6945, and 6961 provides voice communication over an IP network. The Cisco Unified IP Phone functions much like a digital business phone, allowing you to place and receive phone calls and to access features such as mute, hold, transfer, speed dial, and call forward. In addition, because the phone is connected to your data network, it offers enhanced IP telephony features, including access to network information and services, and customizable features and services.

A Cisco Unified IP Phone, like other network devices, must be configured and managed. These phones encode G.711a, G.711mu, G.729, G.729a, G.729ab, and iLBC codecs, and decode G.711a, G.711mu, G.729, G.729a, 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 may cause interference. For more information, see the manufacturer documentation of the interfering device.

Supported Network Protocols

Cisco Unified IP Phones support several industry-standard and Cisco network protocols required for voice communication. The following table provides an overview of the network protocols that the Cisco Unified IP Phone 6921, 6941, 6945, and 6961 support.

Table 1 Supported network protocols on the Cisco Unified IP Phone

Network protocol

Purpose

Usage notes

Bootstrap Protocol (BootP)

BootP enables a network device such as the Cisco Unified IP Phone to discover certain startup information, such as its IP address.

Cisco Audio Session Tunneling (CAST)

The CAST protocol allows IP phones and associated applications behind the phone to discover and communicate with the remote endpoints without requiring changes to the traditional signaling components like Cisco Unified Communications Manager and gateways. The CAST protocol allows separate hardware devices to synchronize related media and it allows PC applications to augment nonvideo-capable phones to become video enabled using the PC as the video resource.

Cisco Discovery Protocol (CDP)

CDP is a device-discovery protocol that runs on all Cisco-manufactured equipment.

Using CDP, a device can advertise its existence to other devices and receive information about other devices in the network.

The Cisco Unified IP Phone uses CDP to communicate information such as auxiliary VLAN ID, per port power management details, and Quality of Service (QoS) configuration information with the Cisco Catalyst switch.

Dynamic Host Configuration Protocol (DHCP)

DHCP dynamically allocates and assigns an IP address to network devices.

DHCP enables you to connect an IP phone into the network and have the phone become operational without your needing to manually assign an IP address or to configure additional network parameters.

DHCP is enabled by default. If disabled, you must manually configure the IP address, subnet mask, gateway, and a TFTP server on each phone locally.

Cisco recommends that you use DHCP custom option 150. With this method, you configure the TFTP server IP address as the option value. For additional supported DHCP configurations, go to the "Dynamic Host Configuration Protocol" chapter and the "Cisco TFTP" chapter in the Cisco Unified Communications Manager System Guide.

Note   

If you cannot use option 150, you may try using DHCP option 66.

Hypertext Transfer Protocol (HTTP)

HTTP is the standard way of transferring information and moving documents across the Internet and the web.

Cisco Unified IP Phones use HTTP for the XML services and for troubleshooting purposes.

Hypertext Transfer Protocol Secure (HTTPS)

Hypertext Transfer Protocol Secure (HTTPS) is a combination of the Hypertext Transfer Protocol with the SSL/TLS protocol to provide encryption and secure identification of servers.

Note   

IP phones can be HTTPS clients; they cannot be HTTPS servers.

Web applications with both HTTP and HTTPS support have two URLs configured. Cisco Unified IP Phones that support HTTPS choose the HTTPS URL.

A lock icon is displayed to the user if the connection to the service is via HTTPS.

IEEE 802.1X

The IEEE 802.1X standard defines a client-server-based access control and authentication protocol that restricts unauthorized clients from connecting to a LAN through publicly accessible ports.

Until the client is authenticated, 802.1X access control allows only Extensible Authentication Protocol over LAN (EAPOL) traffic through the port to which the client is connected. After authentication is successful, normal traffic can pass through the port.

The Cisco Unified IP Phone implements the IEEE 802.1X standard by providing support for the following authentication methods: EAP-FAST, EAP-TLS, and EAP-MD5.

When 802.1X authentication is enabled on the phone, you should disable the PC port and voice VLAN. Refer to the 802.1X Authentication for additional information.

Internet Protocol (IP)

IP is a messaging protocol that addresses and sends packets across the network.

To communicate using IP, network devices must have an assigned IP address, subnet, and gateway.

IP addresses, subnets, and gateways identifications are automatically assigned if you are using the Cisco Unified IP Phone with Dynamic Host Configuration Protocol (DHCP). If you are not using DHCP, you must manually assign these properties to each phone locally.

The Cisco Unified IP Phones support IPv6 address. For more information, see "Internet Protocol Version 6 (IPv6)" in the Cisco Unified Communications Manager Features and Services Guide.

Link Layer Discovery Protocol (LLDP)

LLDP is a standardized network discovery protocol (similar to CDP) that is supported on some Cisco and third-party devices.

The Cisco Unified IP Phone supports LLDP on the PC port.

Link Layer Discovery Protocol-Media Endpoint Devices (LLDP-MED)

LLDP-MED is an extension of the LLDP standard developed for voice products.

The Cisco Unified IP Phone supports LLDP-MED on the SW port to communicate information such as:

  • Voice VLAN configuration
  • Device discovery
  • Power management
  • Inventory management

For more information about LLDP-MED support, see the LLDP-MED and Cisco Discovery Protocol white paper:http:/​/​www.cisco.com/​en/​US/​tech/​tk652/​tk701/​technologies_​white_​paper0900aecd804cd46d.shtml

Real-Time Transport Protocol (RTP)

RTP is a standard protocol for transporting real-time data, such as interactive voice and video, over data networks.

Cisco Unified IP Phones use the RTP protocol to send and receive real-time voice traffic from other phones and gateways.

Real-Time Control Protocol (RTCP)

RTCP works in conjunction with RTP to provide QoS data (such as jitter, latency, and round trip delay) on RTP streams.

RTCP is disabled by default, but you can enable it on a per phone basis by using Cisco Unified Communications Manager.

Session Initiation Protocol (SIP)

SIP is the Internet Engineering Task Force (IETF) standard for multimedia conferencing over IP. SIP is an ASCII-based application-layer control protocol (defined in RFC 3261) that can be used to establish, maintain, and terminate calls between two or more endpoints.

Like other VoIP protocols, SIP is designed to address the functions of signaling and session management within a packet telephony network. Signaling allows call information to be carried across network boundaries. Session management provides the ability to control the attributes of an end-to-end call.

You can configure the Cisco Unified IP Phone to use either SIP or Skinny Client Control Protocol (SCCP). Cisco Unified IP Phones do not support the SIP protocol when the phones are operating in IPv6 address mode.

Skinny Client Control Protocol (SCCP)

SCCP includes a messaging set that allows communications between call control servers and endpoint clients such as IP Phones. SCCP is proprietary to Cisco Systems.

Cisco Unified IP Phone 6921, 6941, 6945, and 6961 use SCCP, version 20 for call control.

Secure Real-Time Transfer protocol (SRTP)

SRTP is an extension of the Real-Time Protocol (RTP) Audio/Video Profile and ensures the integrity of RTP and Real-Time Control Protocol (RTCP) packets providing authentication, integrity, and encryption of media packets between two endpoints.

Cisco Unified IP Phones use SRTP for media encryption.

Transmission Control Protocol (TCP)

TCP is a connection-oriented transport protocol.

Cisco Unified IP Phones use TCP to connect to Cisco Unified Communications Manager and to access XML services.

Transport Layer Security (TLS)

TLS is a standard protocol for securing and authenticating communications.

When security is implemented, Cisco Unified IP Phones use the TLS protocol when securely registering with Cisco Unified Communications Manager.

For more information, see Cisco Unified Communications Manager Security Guide.

Trivial File Transfer Protocol (TFTP)

TFTP allows you to transfer files over the network.

On the Cisco Unified IP Phone, TFTP enables you to obtain a configuration file specific to the phone type.

TFTP requires a TFTP server in your network, which can be automatically identified from the DHCP server. If you want a phone to use a TFTP server other than the one specified by the DHCP server, you must manually assign the IP address of the TFTP server by using the Network Setup menu on the phone.

For more information, see "Cisco TFTP" chapter in the Cisco Unified Communications Manager System Guide.

User Datagram Protocol (UDP)

UDP is a connectionless messaging protocol for delivery of data packets.

Cisco Unified IP Phones transmit and receive RTP streams, which utilize UDP.

Cisco Unified IP Phone 6921, 6941, 6945, and 6961 Supported Features

Cisco Unified IP Phones function much like a digital business phone, allowing you to place and receive phone calls. In addition to traditional telephony features, the Cisco Unified IP Phone includes features that enable you to administer and monitor the phone as a network device.

Feature Overview

Cisco Unified IP Phones provide traditional telephony functionality, such as call forwarding and transferring, redialing, speed dialing, conference calling, and voice messaging system access. Cisco Unified IP phones also provide a variety of other features.

As with other network devices, you must configure Cisco Unified IP Phones to prepare them to access Cisco Unified Communications Manager and the rest of the IP network. By using DHCP, you have fewer settings to configure on a phone, but if your network requires it, you can manually configure an IP address, TFTP server, and subnet information.

Cisco Unified IP Phones can interact with other services and devices on your IP network to provide enhanced functionality. For example, you can integrate Cisco Unified Communications Manager with the corporate Lightweight Directory Access Protocol 3 (LDAP3) standard directory to enable users to search for coworker contact information directly from their IP phones. You can also use XML to enable users to access information such as weather, stocks, quote of the day, and other web-based information.

Finally, because the Cisco Unified IP Phone is a network device, you can obtain detailed status information from it directly. This information can assist you with troubleshooting any problems users might encounter when using their IP phones.

Cisco Unified IP Phone Security Features

Implementing security in the Cisco Unified Communications Manager system prevents identity theft of the phone and Cisco Unified Communications Manager server, prevents data tampering, and prevents call signaling and media stream tampering.

To alleviate these threats, the Cisco IP telephony network establishes and maintains secure communication streams between a phone and the server, digitally signs files before they are transferred to a phone, and encrypts media streams and call signaling between Cisco Unified IP Phones.

The Cisco Unified IP Phone 6921, 6941, 6945, and 6961 use the Phone security profile, which defines whether the device is nonsecure or encrypted. For information on applying the security profile to the phone, see Cisco Unified Communications Manager Security Guide.

If you configure security-related settings in Cisco Unified Communications Manager Administration, the phone configuration file will contain sensitive information. To ensure the privacy of a configuration file, you must configure it for encryption. For detailed information, see "Configuring Encrypted Phone Configuration Files" chapter in Cisco Unified Communications Manager Security Guide.

The following table shows where you can find additional information about security in this and other documents.

Table 3 Overview of Security Features

Feature

Description

Image authentication

Signed binary files (with the extension .sgn) prevent tampering with the firmware image before it is loaded on a phone. Tampering with the image causes a phone to fail the authentication process and reject the new image.

Customer-site certificate installation

Each Cisco Unified IP Phone requires a unique certificate for device authentication. Phones include a manufacturing installed certificate (MIC), but for additional security, you can specify in Cisco Unified Communications Manager Administration that a certificate be installed by using the Certificate Authority Proxy Function (CAPF). Alternatively, you can install a Locally Significant Certificate (LSC) from the Security Configuration menu on the phone.

Device authentication

Occurs between the Cisco Unified Communications Manager server and the phone when each entity accepts the certificate of the other entity. Determines whether a secure connection between the phone and a Cisco Unified Communications Manager should occur; and, if necessary, creates a secure signaling path between the entities by using TLS protocol. Cisco Unified Communications Manager will not register phones unless they can be authenticated by the Cisco Unified Communications Manager.

File authentication

Validates digitally signed files that the phone downloads. The phone validates the signature to make sure that file tampering did not occur after the file creation. Files that fail authentication are not written to Flash memory on the phone. The phone rejects such files without further processing.

Signaling Authentication

Uses the TLS protocol to validate that no tampering has occurred to signaling packets during transmission.

Manufacturing installed certificate

Each Cisco Unified IP Phone contains a unique manufacturing installed certificate (MIC), which is used for device authentication. The MIC is a permanent unique proof of identity for the phone, and allows Cisco Unified Communications Manager to authenticate the phone.

Secure SRST reference

After you configure a SRST reference for security and then reset the dependent devices in Cisco Unified Communications Manager Administration, the TFTP server adds the SRST certificate to the phone cnf.xml file and sends the file to the phone. A secure phone then uses a TLS connection to interact with the SRST-enabled router.

Media encryption

Uses SRTP to ensure that the media streams between supported devices proves secure and that only the intended device receives and reads the data. Includes creating a media master key pair for the devices, delivering the keys to the devices, and securing the delivery of the keys while the keys are in transport.

Signaling encryption

Ensures that all SCCP signaling messages that are sent between the device and the Cisco Unified Communications Manager server are encrypted.

CAPF (Certificate Authority Proxy Function)

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. The CAPF can be configured to request certificates from customer-specified certificate authorities on behalf of the phone, or it can be configured to generate certificates locally.

Security profiles

Defines whether the phone is nonsecure or encrypted.

Encrypted configuration files

Lets you ensure the privacy of phone configuration files.

Optional disabling of the web server functionality for a phone

You can prevent access to a phone web page, which displays a variety of operational statistics for the phone.

Phone hardening

Additional security options, which you control from Cisco Unified Communications Manager Administration:

  • Disabling PC port
  • Disabling PC Voice VLAN access
  • Disabling access to web pages for a phone
Note   

You can view current settings for the PC Port Disabled, GARP Enabled, and Voice VLAN enabled options by looking at the phone Security Configuration menu.

802.1X Authentication

The Cisco Unified IP Phone can use 802.1X authentication to request and gain access to the network.

Security Profiles

All Cisco Unified IP Phones that support Cisco Unified Communications Manager use a security profile, which defines whether the phone is nonsecure or encrypted. For information about configuring the security profile and applying the profile to the phone, see the Cisco Unified Communications Manager Security Guide.

To view the security mode that is set for the phone, look at the Security Mode setting in the Security Configuration menu.

Encrypted Phone Call Identification

When security is implemented for a phone, you can identify encrypted phone calls by icons on the screen on the phone. You can also determine if the connected phone is secure and protected if a security tone plays at the beginning of the call.

In a secure call, all call signaling and media streams are encrypted. An encrypted call offers a high level of security, providing integrity and privacy to the call. When a call in progress is being encrypted, the call progress icon to the right of the call duration timer in the phone LCD screen changes to the lock icon: .

If the call is routed through non-IP call legs, for example, PSTN, the call may be nonsecure even though it is encrypted within the IP network and has a lock icon associated with it.

In a secure call, a security tone plays at the beginning of a call to indicate that the other connected phone is also receiving and transmitting encrypted audio and video (if video is involved). If your call is connected to a non-protected phone, the security tone does not play.


Note


Secured calling is supported for connections between two phones only. Some features, such as conference calling, shared lines, Cisco Extension Mobility, and Join Across Lines are not available when secured calling is configured.


Identify Secure Conference Call

You can initiate a secure conference call and monitor the security level of participants. A secure conference call is established using this process:

  1. A user initiates the conference from a secure phone.
  2. Cisco Unified Communications Manager assigns a secure conference bridge to the call.
  3. As participants are added, Cisco Unified Communications Manager verifies the security mode of each phone and maintains the secure level for the conference.
  4. The phone displays the security level of the conference call. A secure conference displays the to the right of Conference on the phone screen.

Note


There are interactions, restrictions, and limitations that affect the security level of the conference call depending on the security mode of the participant phones and the availability of secure conference bridges.


Identify Secure Phone Call

A protected call is established when your phone and the phone on the other end are configured for protected calling. The other phone can be in the same Cisco IP network or on a network outside the IP network. Protected calls can only be made between two phones. Conference calls and other multiple-line calls cannot be protected.

A protected call is established using this process:

  1. A user initiates the call from a protected phone (protected security mode).
  2. The phone displays the icon (encrypted) on the phone screen. This icon indicates that the phone is configured for secure (encrypted) calls, but this does not mean that the other connected phone is also protected.
  3. A security tone plays if the call is connected to another protected phone, indicating that both ends of the conversation are encrypted and protected. If the call is connected to a unprotected phone, then the secure tone does not play.

Note


Protected calling is supported for conversations between two phones. Some features, such as conference calling, shared lines, Cisco Extension Mobility, and Join Across Lines are not available when protected calling is configured.


Call Security Interactions and Restrictions

Cisco Unified Communications Manager checks the phone security status when conferences are established and changes the security indication for the conference or blocks the completion of the call to maintain integrity and security in the system. The following table provides information about changes to call security levels when using Barge.

802.1X Authentication

These sections provide information about 802.1X support on the Cisco Unified IP Phones.

Related Information

Overview

Cisco Unified IP Phones and Cisco Catalyst switches traditionally use Cisco Discovery Protocol (CDP) to identify each other and determine parameters such as VLAN allocation and inline power requirements. CDP does not identify locally attached workstations. 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.

Cisco Unified IP Phones also provide a proxy EAPOL Logoff mechanism. In the event that the locally attached PC disconnects from the IP phone, the LAN switch does not see the physical link fail, because the link between the LAN switch and the IP phone is maintained. To avoid compromising network integrity, the IP phone sends an EAPOL-Logoff message to the switch on behalf of the downstream PC, which triggers the LAN switch to clear the authentication entry for the downstream PC.

Cisco Unified IP Phones also contain an 802.1X supplicant. This supplicant allows network administrators to control the connectivity of IP phones to the LAN switch ports. The current release of the phone 802.1X supplicant uses the EAP-FAST, EAP-TLS, and EAP-MD5 options for network authentication.

Required Network Components

Support for 802.1X authentication on Cisco Unified IP Phones requires several components, including:

  • Cisco Unified IP Phone: The phone acts as the 802.1X supplicant, which initiates the request to access the network.
  • Cisco Secure Access Control Server (ACS) (or other third-party authentication server): The authentication server and the phone must both be configured with a shared secret that authenticates the phone.
  • 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.

Best Practices, Requirements and Recommendations

  • Enable 802.1X Authentication: If you want to use the 802.1X standard to authenticate Cisco Unified IP Phones, be sure that you have properly configured the other components before enabling it on the phone. For more information, see the 802.1X Authentication and Status.
  • Configure PC Port: The 802.1X standard does not take into account the use of VLANs and thus recommends that only a single device should be authenticated to a specific switch port. However, some switches (including Cisco Catalyst switches) support multi-domain authentication. The switch configuration determines whether you can connect a PC to the phone PC port.
    • Enabled: If you are using a switch that supports multi-domain authentication, you can enable the PC port and connect a PC to it. In this case, Cisco Unified IP Phones support proxy EAPOL-Logoff to monitor the authentication exchanges between the switch and the attached PC. For more information about IEEE 802.1X support on the Cisco Catalyst switches, see Cisco Catalyst switch configuration guides at: http:/​/​www.cisco.com/​en/​US/​products/​hw/​switches/​ps708/​tsd_​products_​support_​series_​home.html
    • Disabled: If the switch does not support multiple 802.1X-compliant devices on the same port, you should disable the PC Port when 802.1X authentication is enabled. For more information, see the Security Setup Menu. If you do not disable this port and subsequently attempt to attach a PC to it, the switch will deny network access to both the phone and the PC.
  • Configure Voice VLAN: Because the 802.1X standard does not account for VLANs, you should configure this setting based on the switch support.
    • Enabled: If you are using a switch that supports multi-domain authentication, you can continue to use the voice VLAN.
    • Disabled: If the switch does not support multi-domain authentication, disable the Voice VLAN and consider assigning the port to the native VLAN. For more information, see the Security Setup Menu.
  • Enter MD5 Shared Secret: If you disable 802.1X authentication or perform a factory reset on the phone, the previously configured MD5 shared secret is deleted. For more information, see the 802.1X Authentication and Status.

Security Restrictions

A user cannot barge into an encrypted call if the phone that is used to barge is not configured for encryption. When barge fails in this case, a reorder (fast busy) tone plays on the phone that the barge was initiated.

If the initiator phone is configured for encryption, the barge initiator can barge into a nonsecure call from the encrypted phone. After the barge occurs, Cisco Unified Communications Manager classifies the call as nonsecure.

If the initiator phone is configured for encryption, the barge initiator can barge into an encrypted call, and the phone indicates that the call is encrypted.

Cisco Unified IP Phone Deployment

When deploying a new IP telephony system, system administrators and network administrators must complete several initial configuration tasks to prepare the network for IP telephony service. For information and a checklist for setting up and configuring a Cisco IP telephony network, see "System Configuration Overview" chapter in Cisco Unified Communications Manager System Guide.

After you have set up the IP telephony system and configured system-wide features in Cisco Unified Communications Manager, you can add IP phones to the system.

Cisco Unified IP Phones Setup in Cisco Unified Communications Manager

To add phones to the Cisco Unified Communications Manager database, you can use:

  • Autoregistration
  • Cisco Unified Communications Manager Administration
  • Bulk Administration Tool (BAT)
  • BAT and the Tool for AutoRegistered Phones Support (TAPS)

For more information about these choices, see Cisco Unified Communications Manager Phone Addition Methods.
