Understanding How the Cisco Unified IP Phone Interacts with Cisco Unified Communications Manager

Cisco Unified Communications Manager is an open and industry-standard call processing system. Cisco Unified Communications Manager software sets up and tears down calls between phones, integrating traditional PBX functionality with the corporate IP network. Cisco Unified Communications Manager manages the components of the IP telephony system—the phones, the access gateways, and the resources necessary for such features as call conferencing and route planning. Cisco Unified Communications Manager also provides:
Firmware for phones
Authentication and encryption (if configured for the telephony system)
Configuration file and CTL file, via TFTP service
Phone registration
Call preservation, so that a media session continues if signaling is lost
between the primary Communications Manager and a phone)

Understanding How the Cisco Unified IP Phone Interacts with the VLAN

The Cisco Unified IP Phone 7961G/7961G-GE and 7941G/7941G-GE have an internal Ethernet switch, enabling forwarding of packets to the phone, and to the access port and the network port on the back of the phone.
If a computer is connected to the access port, the computer and the phone share the same physical link to the switch and share the same port on the switch. This shared physical link has the following implications for the VLAN configuration on the network:
The current VLANs might be configured on an IP subnet basis. However,
additional IP addresses might not be available to assign the phone to the same subnet as other devices connected to the same port.
Data traffic present on the VLAN supporting phones might reduce the quality
of Voice-over-IP traffic.
Network security may indicate a need to isolate the VLAN voice traffic from
the VLAN data traffic.

Providing Power to the Cisco Unified IP Phone

You can resolve these issues by isolating the voice traffic onto a separate VLAN. The switch port that the phone is connected to would be configured to have separate VLANs for carrying:
Voice traffic to and from the IP phone (auxiliary VLAN on the Cisco Catalyst
6000 series, for example)
Data traffic to and from the PC connected to the switch through the access
port of the IP phone (native VLAN)
Isolating the phones on a separate, auxiliary VLAN increases the quality of the voice traffic and allows a large number of phones to be added to an existing network where there are not enough IP addresses for each phone.

Understanding Phone Configuration Files
Configuration files for a phone are stored on the TFTP server and define parameters for connecting to Cisco Unified Communications Manager. In general, any time you make a change in Cisco Unified Communications Manager that requires the phone to be reset, a change is made to the phone’s configuration file automatically.
Configuration files also contain information about which image load the phone should be running. If this image load differs from the one currently loaded on a phone, the phone contacts the TFTP server to request the required load files. (These files are digitally signed to ensure the authenticity of the files’ source.)
In addition, if the device security mode in the configuration file is set to Authenticated and the CTL file on the phone has a valid certificate for Cisco Unified Communications Manager, the phone establishes a TLS connection to Cisco Unified Communications Manager. Otherwise, the phone establishes a TCP connection. For SIP phones, a TLS connection requires that the transport

protocol in the phone configuration file be set to TLS, which corresponds to the transport type in the SIP Security Profile in Cisco Unified Communications Manager.
Note If the device security mode in the configuration file is set to Authenticated or
Encrypted, but the phone has not received a CTL file, the phone will continuously try to obtain a CTL file so that it can register securely.
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.A phone requests a configuration file whenever it resets and registers with Cisco Unified Communications Manager.
A phone accesses a default configuration file named XmlDefault.cnf.xml from the TFTP server when the following conditions exist:
You have enabled auto-registration in Cisco Unified Communications
Manager
Understanding Phone Configuration Files
The phone has not been added to the Cisco Unified Communications
Manager Database
The phone is registering for the first time
If auto registration is not enabled and the phone has not been added to the Cisco Unified Communications Manager Database, the phone registration request will be rejected. In this case, the phone will reset and attempt to register repeatedly.
If the phone has registered before, the phone will access the configuration file named SEPmac_address.cnf.xml, where mac_address is the MAC address of the phone.
The TFTP server generates these SIP configuration files:
SIP IP Phone:
For unsigned and unencrypted files—SEP<mac>.cnf.xml
For signed files—SEP<mac>.cnf.xml.sgn
For signed and encrypted files—SEP<mac>.cnf.xml.enc.sgn

Understanding the Phone Startup Process
When connecting to the VoIP network, the Cisco Unified IP Phone 7961G/7961G-GE and 7941G/7941G-GE go through a standard startup process that is described in Tabl e 2-4. Depending on your specific network configuration, not all of these steps may occur on your Cisco Unified IP Phone.

If a phone is not using external power, the switch provides in-line power through the Ethernet cable attached to the phone.
The Cisco Unified IP Phone has non-volatile Flash memory in which it stores firmware images and user-defined preferences. At startup, the phone runs a bootstrap loader that loads a phone image stored in Flash memory. Using this image, the phone initializes its software and hardware.

3. Configuring VLAN If the Cisco Unified IP Phone is connected to a
Cisco Catalyst switch, the switch next informs the phone of the voice VLAN defined on the switch. The phone needs to know its VLAN membership before it can proceed with the Dynamic Host Configuration Protocol (DHCP) request for an IP address.
4. Obtaining an IP
Address
If the Cisco Unified IP Phone is using DHCP to obtain an IP address, the phone queries the DHCP server to obtain one. If you are not using DHCP in your network, you must assign static IP addresses to each phone locally.
5. Accessing a TFTP
Server
In addition to assigning an IP address, the DHCP server directs the Cisco Unified IP Phone to a TFTP Server. If the phone has a statically-defined IP address, you must configure the TFTP server locally on the phone; the phone then contacts the TFTP server directly.
Note You can also assign an alternative TFTP
server to use instead of the one assigned by DHCP.
6. Requesting the CTL
file
The TFTP server stores the certificate trust list (CTL) file. This file contains a list of Cisco Unified Communications Managers and TFTP servers that the phone is authorized to connect to. It also contains the certificates necessary for establishing a secure connection between the phone and Cisco Unified Communications Manager.

7. Requesting the
Configuration File
8. Contacting Cisco Unified Communicatio ns Manager
The TFTP server has configuration files, which define parameters for connecting to Cisco Unified Communications Manager and other information for the phone.
The configuration file defines how the Cisco Unified IP Phone communicates with Cisco Unified Communications Manager and provides a phone with its load ID. After obtaining the file from the TFTP server, the phone attempts to make a connection to the highest priority Cisco Unified Communications Manager on the list. If security is implemented, the phone makes a TLS connection. Otherwise, it makes a non-secure TCP connection.
If the phone was manually added to the database, Cisco Unified Communications Manager identifies the phone. If the phone was not manually added to the database and auto-registration is enabled in Cisco Unified Communications Manager, the phone attempts to auto-register itself in the Cisco Unified Communications Manager database.
