What Networking Protocols Are Used?

Cisco Unified IP Phones support several industry-standard and Cisco networking protocols required for voice communication. Table 1-1 provides an overview of the networking protocols that the Cisco Unified IP Phones 7970G/7971G-GE supports.

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

Networking 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.

If you are using BootP to assign IP addresses to the Cisco Unified IP Phone, the BOOTP Server option shows "Yes" in the network configuration settings on the phone.

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 you 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 DCHP configurations, refer to Cisco Unified CallManager System Guide.

HyperText Transfer Protocol (HTTP)

HTTP is the standard way of transferring information and moving documents across the Internet and the World Wide Web.

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

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.

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.

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.

You can configure the Cisco Unified IP Phone to use either SCCP or Session Initiation Protocol (SIP).

Session Initiation Protocol (SIP)

SIP is an emerging standard for setting up telephone calls, multimedia conferencing, and other types of communications on the Internet.

You can configure the Cisco Unified IP Phone to use either SCCP or SIP.

Session Description Protocol (SDP)

Session Description Protocol (SDP) is the portion of the SIP protocol that determines which parameters are available during a connection between two endpoints. Conferences are established 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 CallManager or Media Gateway in operation. Some SIP endpoints may allow these parameters to be configured on the end point itself. This may vary from vendor to vendor.

Transmission Control Protocol (TCP)

TCP is a connection-oriented transport protocol.

Cisco Unified IP Phones use TCP to connect to Cisco Unified CallManager 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 CallManager.

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 TFTP server from the Network Configuration menu on the phone.

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.

Understanding the SIP Protocol

Session Initiation Protocol (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.

What Features are Supported on the Cisco Unified IP Phones 7970G/7971G-GE?

The Cisco Unified IP Phone functions much like a digital business phone, allowing you to place and receive telephone 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 covers 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, see the "Telephony Features Available for the Phone" section on page 5-2.

As with other network devices, you must configure Cisco Unified IP Phones to prepare them to access Cisco Unified CallManager and the rest of the IP network. By using DHCP, you have fewer settings to configure on a phone, but can manually configure an IP address, TFTP server, and subnet mask if your network requires it. For instructions on configuring the network settings on the Cisco Unified IP Phones, see "Configuring Settings on the Cisco Unified IP Phone."

The Cisco Unified IP Phone can interact with other services and devices on your IP network to provide enhanced functionality. For example, you can integrate the Cisco Unified IP Phones with the corporate Lightweight Directory Access Protocol 3 (LDAP3) standard directory to enable users to search for co-workers 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 Directories and Personal Directories" section on page 5-13 and the "Setting Up Services" section on page 5-15.

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

Understanding Security Features for Cisco Unified IP Phones

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

To alleviate these threats, the Cisco IP telephony network establishes and maintains authenticated and 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 Phones 7970G/7971G-GE (SIP) use the SIP Phone security profile, which defines whether the device is nonsecure, authenticated, or encrypted. For information on applying the security profile to the phone, refer to the Cisco Unified CallManager Security Guide.

If you configure security-related settings in Cisco Unified CallManager 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 CallManager Security Guide.

Table 1-2 shows where you can find additional information about security in this and other documents.

Note Most security features are available only if a certificate trust list (CTL) is installed on the phone. For more information about the CTL, refer to Cisco Unified CallManager Security Guide.


Table 1-3 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.

Customer-site certificate installation

Each Cisco Unified IP Phone requires a unique certificate for device authentication. Phones include a manufacturing installed certificate, but for additional security, you can specify in Cisco Unified CallManager Administration that a certificate be installed by using the CAPF. Alternatively, you can initiate the installation of an LSC from the Security Configuration menu on the phone.

Device authentication

Occurs between the Cisco Unified CallManager 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 CallManager should occur, and, if necessary, creates a secure signaling path between the entities using TLS protocol. Cisco Unified CallManager will not register phones unless they can be authenticated by the Cisco Unified CallManager.

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 CallManager 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.

Signaling Encryption

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

CAPF (Certificate Authority Proxy Function)

Implements parts of the certificate generation procedure that are too processing-intensive for the phone, and it 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, or encrypted.

Encrypted Configuration files

Enables privacy of phone configuration files.

Optional disabling of the web server functionality for a phone

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

Phone hardening

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

Disabling PC port

Disabling Gratuitous ARP

Disabling PC Voice VLAN access

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

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's Security Configuration menu. For more information, see the "Device Configuration Menu" section.

Identifying Encrypted and Authenticated Phone Calls

When security is implemented for a phone, you can identify authenticated or encrypted phone calls by icons on the LCD screen on the phone.

In an authenticated call, all devices participating in the establishment of the call are authenticated by the Cisco Unified CallManager. When a call in progress is authenticated end-to-end, the call progress icon to the right of the call duration timer in the phone LCD screen changes to the following icon:

In an encrypted call, all devices participating in the establishment of the call are authenticated by the Cisco Unified CallManager. In addition, call signaling and media streams are encrypted. An encrypted call offers the highest 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 following icon:


Note If the call is routed through non-IP call legs, for example, H.323 or PSTN, the call will be nonsecure even though it is encrypted within the IP network and has a lock icon associated with it.

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 an authenticated or nonsecure call from the encrypted phone. After the barge occurs, Cisco Unified CallManager 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.

A user can barge into an authenticated call, even if the phone that is used to barge is nonsecure. The authentication icon continues to appear on the authenticated devices in the call, even if the initiator phone does not support security.
