An Overview of the Cisco Unified IP Phone


The Cisco Unified IP Phone 8961, 9951, and 9971 provide 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 and to access features such as mute, hold, transfer, speed dial, call forward, and more. 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 customizeable features and services.

The Cisco Unified IP Phone 8961, 9951, and 9971 have the following features:

24-bit color phone screen (Cisco Unified IP Phone 9971 has touchscreen support)

Programmable feature buttons that support up to 5 lines (6 lines for the Cisco Unified IP Phone 9971) or can be programmed for other features

Full video capabilities (Cisco Unified IP Phone 9951 and 9971 only)

Gigabit ethernet connectivity

Support for an external microphone and speakers

Bluetooth support for wireless headsets (Cisco Unified IP Phone 9951 and 9971 only)

Network connectivity by Wi-Fi (Cisco Unified IP Phone 9971 only)

2 USB ports for Cisco Unified IP Phones 9951 and 9971 and one USB port for Cisco Unified IP Phone 8961

A Cisco Unified IP Phone, like other network devices, must be configured and managed. These phones encode G.711a-law, G.711µ-law, G.722, G.729a, G.729ab, and iLBC, and decode G.711a-law, G.711µ-law, G.722, G.729, G.729a, G.729b, G.729ab, and iLBC.

What Networking Protocols are Used?

Cisco Unified IP Phones support several industry-standard and Cisco networking protocols required for voice communication. Table 1-4 provides an overview of the networking protocols that the Cisco Unified IP Phone 8961, 9951, and 9971 support.

Table 1-4 Supported Networking Protocols on the Cisco Unified IP Phone 

Networking Protocol
Purpose
Usage Notes

Bluetooth

Bluetooth is a wireless personal area network (WPAN) protocol that specifies how devices communicate over short distances.

Cisco Unified IP Phone 9951 and 9971 support Bluetooth 2.1

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 Tunnel (CAST)

The CAST protocol allows the Cisco Unified IP Phones and associated applications to discover and communicate with the remote IP phones without requiring changes to the traditional signaling components such as Cisco Unified CM and gateways.

The Cisco Unified IP Phone uses CAST as an interface between CUVA and Unified CM using the Cisco IP Phone as a SIP proxy.

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.

Cisco Peer-to-Peer Distribution Protocol (CPPDP)

CPPDP is a Cisco proprietary protocol used to form a peer to peer hierarchy of devices. This hierarchy is used to distribute firmware files from peer devices to their neighboring devices.

CPPDP is used by the Peer Firmware Sharing feature.

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.

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

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 "Supporting 802.1X Authentication on Cisco Unified IP Phones" section for additional information.

IEEE 802.11a/b/g

The IEEE 802.11 standard specifies how devices communication over a wireless local area network (WLAN).

802.11a operates at the 5 GHz band and 802.11b and 802.11g operate at the 2.4 GHz band

(Cisco Unified IP Phone 9971 only) The 802.11 interface is a deployment option for cases when Ethernet cabling is unavailable or undesirable.

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.

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 Description Protocol (SDP)

SDP is the portion of the SIP protocol that determines which parameters are available during a connection between two endpoints. Conferences are established by using only the SDP capabilities that are supported by all endpoints in the conference.

SDP capabilities, such as codec types, DTMF detection, and comfort noise, are normally configured on a global basis by Cisco Unified Communications Manager or Media Gateway in operation. Some SIP endpoints may allow these parameters to be configured on the endpoint itself.

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.

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 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.

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 Configuration menu on the phone.

For more information, go to the 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.

What Features are Supported on the Cisco Unified IP Phone 8961, 9951, and 9971?

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.

This section includes the following topics:

Feature Overview

Configuring Telephony Features

Configuring Network Parameters Using the Cisco Unified IP Phone

Providing Users with Feature Information

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. For an overview of the telephony features that the Cisco Unified IP Phone supports and for tips on configuring them, see the "Telephony Features Available for the Cisco Unified IP Phone" section.

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, subnet information, and so on. For instructions on configuring the network settings on the Cisco Unified IP Phones, see Chapter 7 "Configuring Settings on the Cisco Unified IP Phone."

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 co-worker 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. For information about configuring such services, see the "Configuring Corporate and Personal Directories" section and the "Setting Up Services" section.

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. See Chapter 10 "Viewing Model Information, Status, and Statistics on the Cisco Unified IP Phone," for more information.

Make sure to visit the Cisco Unified IP Phone web site:

http://www.cisco.com/en/US/products/ps10453/products_user_guide_list.html

From this site, you can view various user guides.

In addition to providing documentation, it is important to inform users of available Cisco Unified IP Phone features, including those specific to your company or network, and of how to access and customize those features, if appropriate.

For a summary of some of the key information that phone users need their system administrators to provide, see "Providing Information to Users Via a Website."

Understanding Security Features for Cisco Unified IP Phones

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 (encrypted) 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 8961, 9951, and 9971 use the Phone security profile, which defines whether the device is nonsecure or secure. For information on applying the security profile to the phone, refer to the 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, refer to the "Configuring Encrypted Phone Configuration Files" chapter in Cisco Unified Communications Manager Security Guide.

Table 1-5 shows where you can find information about security in this and other documents.

Overview of Supported Security Features

Table 1-6 provides an overview of the security features that the Cisco Unified IP Phone 8961, 9951, and 9971 support. For more information about these features and about Cisco Unified Communications Manager and Cisco Unified IP Phone security, refer to Cisco Unified Communications Manager Security Guide.

For information about current security settings on a phone, press and choose Administrator Settings > Security Setup. For more information, see the "Security Setup Menu" section.

Table 1-6 Overview of Security Features 

Feature
Description

Image authentication

Signed binary files (with the extension .sbn) 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.

Image Encryption

Encrypted binary files (with the extension .sebn) 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. See the "Configuring Security on the Cisco Unified IP Phone" section for more information.

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.

File encryption

Encryption prevents sensitive information from being revealed while the file is in transit to the phone. In addition 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.

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.

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, authenticated, encrypted, or protected. See Table 1-6, which provides an overview of the security features that the Cisco Unified IP Phone 9971 supports. For more information about these features and about Cisco Unified Communications Manager and Cisco Unified IP Phone security, refer to the Cisco Unified Communications Manager Security Guide.

Encrypted configuration files

Lets you ensure the privacy of phone configuration files.

Optional disabling of the web server functionality for a phone

For security purposes, you can prevent access to a phone's web page (which displays a variety of operational statistics for the phone) and user options pages. For more information, see the "Enabling and Disabling Web Page Access" section.

Phone hardening

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

Disabling PC port

Disabling Gratuitous ARP (GARP)

Disabling PC Voice VLAN access

Disabling access to the Setting menus, or providing restricted access that allows access to the Preferences menu and saving volume changes only

Disabling access to web pages for a phone

Disabling Bluetooth Accessory Port

802.1X Authentication

The Cisco Unified IP Phone can use 802.1X authentication to request and gain access to the network. See the "Supporting 802.1X Authentication on Cisco Unified IP Phones" section for more information.

Secure SIP Failover for SRST

After you configure an SRST reference for security and then reset the dependent devices in Cisco Unified CM 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.

Signaling encryption

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

Identifying Secure (Encrypted) Phone Calls

When security is implemented for a phone, you can identify secure phone calls by icons on the phone screen. 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. A secure 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 screen changes to the following icon: .


Note 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 secure audio and video (if video is involved). If your call is connected to a non-secure phone, the security tone does not play.


Note Secure calling is supported for connections between two phones only. Some features, such as conference calling, shared lines, and Extension Mobility are not available when secure calling is configured.

Security Restrictions

Establishing and Identifying Secure Conference Calls

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 icon 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's phones and the availability of secure conference bridges. See Table 1-7 and Table 1-8 for information about these interactions.


Establishing and Identifying Secure Calls

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

A secured call is established using this process:

1. A user initiates the call from a secured phone (secured security mode).

2. The phone displays the icon (secure) on the phone screen. This icon indicates that the phone is configured for secure calls, but this does not mean that the other connected phone is also secured.

3. A security tone plays if the call is connected to another secured phone, indicating that both ends of the conversation are encrypted and secured. If the call is connected to a non-secured phone, then the secure tone is not played.


Note Secured calling is supported for conversations between two phones. Some features, such as conference calling, shared lines, and Cisco Extension Mobility are not available when secured 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 also security in the system. Table 1-7 provides information about changes to call security levels when using Barge.

Supporting 802.1X Authentication on Cisco Unified IP Phones

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

Overview

Required Network Components

Best Practices—Requirements and Recommendations

Overview

Cisco Unified IP phones and Cisco Catalyst switches have traditionally used Cisco Discovery Protocol (CDP) to identify each other and determine parameters such as VLAN allocation and inline power requirements. However, CDP is not used to identify any locally attached PCs; therefore, Cisco Unified IP Phones provide an EAPOL pass-through mechanism, whereby a PC locally attached to the IP phone, may pass through EAPOL messages to the 802.1X authenticator in the LAN switch. This prevents the IP phone from having to act as the authenticator, yet allows the LAN switch to authenticate a data endpoint prior to accessing the network.

In conjunction with the EAPOL pass-through mechanism, Cisco Unified IP Phones provide a proxy EAPOL-Logoff mechanism. In the event that the locally attached PC is disconnected from the IP phone, the LAN switch would 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.

The Cisco Unified IP phones also contain an 802.1X supplicant, in addition to the EAPOL pass-through mechanism. 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 is used to authenticate 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. When the exchange is completed, the switch then 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. See the "802.1X Authentication and Transaction Status" section for more information.

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's 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, refer to the 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. See the "Ethernet Setup Menu" section for more information. 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. See the "Ethernet Setup Menu" section for more information.

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. See the "802.1X Authentication and Transaction Status" section for more information.

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 tone (fast busy tone) plays on the phone on which the user initiated the barge.

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.
