Installing and Configuring Cisco 7940/7960

Series IP Phones

Introduction

The 7940/7960 IP Phone models from Cisco provide easy-to-use displays, modern styles, and broad

ranges of features. The 7940 offers two lines, while the 7960 offers six lines for increased productivity.

The 7940 and 7960 are interoperable with ADTRAN’s NetVanta Enterprise Communications Server and

can be autodetected and configured with ease. The purpose of this technical note is to provide instructions

for installing and configuring Cisco phones with the NetVanta Enterprise Communications Server.

Known Integration Issues

There are no known integration issues at this time.

Enabling Cisco SIP Phone Configuration

This section describes how to install the Cisco configuration files and phone firmware so that Cisco 79x0

phones can be automatically detected and provisioned by the UC server.

Obtaining Firmware Upgrades

The UC server supports Cisco 79x0 session initiation protocol (SIP) firmware version P0S3-08-9-00.

ADTRAN does not distribute Cisco firmware, so you must obtain the firmware files from Cisco Systems

(http://www.cisco.com) or from your authorized Cisco reseller.

NOTE: You must have a maintenance contract with Cisco to access the firmware upgrades on Cisco’s

corporate website.

The firmware files obtained from Cisco must be comprised of the following:

P0S3-08-9-00.loads

P0S3-08-9-00.sb2

P0S3-08-9-00.bin

P0S3-08-9-00.sbn

Installing the Configuration Files

Included with this technical note is a folder containing configuration files and templates used by the UC

server to automatically detect and provision Cisco 79x0 Series telephones. This folder must be copied into

the UC server folder tree (along with the Cisco SIP firmware files as outlined above in Obtaining

Firmware Upgrades on page 1).

To install the configuration files:

1. Extract the Cisco folder from the .zip file titled Cisco (7940, 7960) Installation and Configuration

(P0S3-08-9-00) (located in the same directory as this document) and copy it under the

PhoneTypes folder located here:

X:\Program Files\ADTRAN\NetVanta UC Server\Data\System\PhoneTypes, where Xis the

drive where the UC server program files are installed.

For example, the resultant path after the folder is copied (henceforth known as the Cisco

PhoneTypes folder) might appear as follows:

C:\Program Files\ADTRAN\NetVanta UC Server\Data\System\PhoneTypes\Cisco

2. Copy the Cisco SIP firmware files (as outlined in Obtaining Firmware Upgrades on page 1) into

the Cisco PhoneTypes folder.

CAUTION: Cisco phones will not automatically upgrade to the correct version if the firmware files

are not copied into the above folder. Failing to upgrade the phones to the correct version may result

in unexpected behavior and/or a loss of functionality.

3. Restart the NetVanta UC Server Application Service.

Select Start > Control Panel > Administrative Tools > Services.

Scroll down and select NetVanta UC Server Application Services.

Right-click the entry and select Restart.

Enabling Support for Cisco SIP Phones

To enable support for Cisco SIP phones:

1. Select Start > All Programs > NetVanta UC Server > Server Configuration Wizard.

2. Select the Phone Types step.

3. Select Next to bypass the welcome screen.

4. Select the check box next to Cisco (see the figure below).

5. Continue through the wizard by selecting Next at each page until the wizard is finished.

Dynamic Host Configuration Protocol (DHCP) Server

Configuration

When a Cisco phone is plugged into the network, it retrieves an IP address from the DHCP server. It also

checks one of the options for the IP address of the Trivial File Transfer Protocol (TFTP) provisioning

server. If this option is not present, Cisco phones do not automatically upgrade their firmware, nor are

they automatically provisioned. For DHCP servers other than Windows® Server 2003 and SBS, consult

the appropriate documentation and complete the option configuration as indicated in Step 3.a.

To configure the DHCP server for Windows Server 2003/2008 and Small Business Server (SBS):

1. Select Start > Control Panel > Administrative Tools > DHCP.

2. Right-click the domain where you want the Cisco phones to be provisioned and select Set

Predefined Options.

3. Look for Option 150.

a. If Option 150 is not already defined, select Add.

Name UC Server Provisioning Server

Data Type IP Address

Code 150

Description UC Server Provisioning Server IP Address

b. If Option 150 is already defined

If it is defined as an IP Address type and the value is the IP address for the UC

server, no action is required.

If it is not defined as an IP Address type and/or the value is not the IP address

for the UC server, automatic detection of the Cisco phones is not possible

unless this option can be changed as per the instructions in Step 3.a.

4. Select OK.

5. Right-click the Scope Options for the domain and select Configure Options.

6. Select the check box next to Option 150.

7. In the IP address field, enter the IP address of the UC server.

8. Select OK.

Preparation

After the firmware and configuration files are installed on the UC server and the DHCP server is

configured, the next step is connecting the phones to the network and waiting for the initial boot. The

initial boot may take a long time to complete if firmware upgrades occur. While this upgrade is

happening, do not unplug the phone.

Validation

After the phone firmware is upgraded and rebooted and the phone is in an idle state, make sure that the

phone is running the correct firmware and has been automatically detected by the UC server.

Firmware Validation

To verify the firmware:

1. From the Cisco phone, select Settings > Status.

2. Scroll down and select Firmware Versions.

3. Examine Application Load ID. It should read P0S3-08-9-00.

If the firmware version listed on the phone does not match the above value, consult the

troubleshooting section at the end of this document.

Automatic Detection Validation

To verify automatic detection:

1. Launch the UC client: select Start > All Programs > UC Client.

2. Log in using the admin authentication or using an authentication with admin profile access.

3. In the Administration menu, select Phones.

4. Sort by the medium access control (MAC) address column and search for the MAC address of the

Cisco phone that you connected to the network. The phone’s MAC address is printed on the

underside of the phone.

If the phone does not appear in the list, consult the troubleshooting section at the end of this

document.

Adding an Identity

You must either have an unused identity that you can add to the phone, or you must create a new

identity/user to associate with the phone. For more information about creating users and identities in the

UC server, refer to the NetVanta UC Server Administrator Guide–Enterprise Communications Edition,

available online at http://kb.adtran.com/.

Associating an Identity with the Phone

After you install the phone and create a user/identity, you must associate that identity with the phone.

To associate the identity with the phone:

1. Launch the UC client by selecting Start > All Programs > UC Client.

2. Log in using the admin authentication or using an authentication with admin profile access.

3. In the Administration menu, select Phones.

4. Double-click the Cisco phone to which you want to associate the identity.

5. Select Add.

6. Select the identity you want to use and select Select.

7. Select OK.

8. Wait for the phone to automatically reboot. This should take under 5 seconds.

If the phone does not reboot automatically, navigate back to the Phones pane in the UC

client, right-click the specific phone and select Restart Phones.

If the phone does not restart at this point, disconnect and reconnect the power to the phone.

9. After the bootup process is complete, the new identity will appear on the phone display.

Troubleshooting

1. The Cisco phone does not appear in the Phones list in the UC client.

Verify the following:

DHCP server Option 150 is present, enabled, and contains the IP address of the UC

server machine.

NetVanta TFTP service is running.

Select Start > Control Panel > Administrative Tools > Services.

Scroll down to NetVanta TFTP Server.

Ensure service is set to Automatic and is running.

Ensure Windows Firewall is not blocking the TFTP port.

Disable Windows Firewall.

Create an exception for the NetVanta TFTP Service program:

For example, C:\Program Files\ADTRAN\NetVanta UC

Server\Bin\TFTPService.exe.

Ensure the Cisco phone family is enabled.

Run the Server Configuration Wizard and ensure that the Cisco phone family

is checked.

If the check box is cleared, perform the steps outlined in Installing the

Configuration Files on page 2.

Ensure Cisco firmware and configuration files are present in the TFTP Server.

Navigate to .\Program Files\ADTRAN\NetVanta UC Server\Data\TFTP.

Ensure (at a minimum) that the following files are present:

SIPDefault.cnf

template.cnf

If not present, perform the steps outlined in Enabling Cisco SIP Phone

Configuration on page 1.

2. The Cisco phone does not download its configuration from the TFTP server after being

assigned an identity with the UC client.

Verify the following:

NetVanta TFTP service is running.

Select Start > Control Panel > Administrative Tools > Services.

Scroll down to NetVanta TFTP Server.

Ensure service is set to Automatic and is running.

Ensure Windows Firewall is not blocking the TFTP port.

Disable Windows Firewall.

Create an exception for the NetVanta TFTP Service program:

For example, C:\Program Files\ADTRAN\NetVanta UC

Server\Bin\TFTPService.exe.

Ensure that configuration files exist for the phone being provisioned.

Navigate to .\Program Files\ADTRAN\NetVanta UC Server\Data\TFTP.

Ensure (at a minimum) that the following files are present:

SIPDefault.cnf

SIP<MAC>.cfg (where <MAC> is the MAC address of the phone being

provisioned)

If not present, redo the steps outlined in Enabling Cisco SIP Phone

Configuration on page 1.

Ensure that the NetVanta UC Server Application Services service has full

permissions for the TFTP folder .\Program Files\ADTRAN\NetVanta UC

Server\Data\TFTP.

3. The Cisco phone does not respond to restart/reload configuration requests from the UC

client, or incorrect identity/identities assigned to the phone.

If you experience the symptoms above, you can reset the protocol settings:

Open a Telnet session to the phone.

Enter the password cisco.

Issue the command erase protflash.

A manual reboot may be required if the phone does not reboot after 10 minutes.

If this does not address the issue, you can perform a factory default reset:

Hold down the #key as soon as the phone starts to power up.

When prompted to enter the factory default key sequence, dial 123456789*0#.
