Telos VX Engine v1.1.1 and VSet v1.1.0 

Software Update Instructions 

20 August, 2012 

TECH SUPPORT 

From time to time, software updates are issued for Telos phone products which include 

feature enhancements, refinements and operational fixes. This document will guide the 

reader through installing updates to the Telos VX VoIP Talkshow System Engine and 

VSet phoneset. 

IMPORTANT – READ BEFORE UPGRADING 

Configuration backups were generally broken in previous versions, and therefore are not 

compatible with v1.1.0 (which fixes this issue). 

Before upgrading to v1.1.0, you should make a backup that works across versions. To do 

this, log in to VX with SSH (user: root, password: element) and run the following: 

cd /flash/config/call_control 

tar -czvf config-backup.tar.gz config tones 

The resulting file can then be copied to your PC with WinSCP (OS X and Linux users 

can use the scp command line utility). To restore, put the file in 

/flash/config/call_control and run: 

tar -xzvf config-backup.tar.gz 

Reboot VX to apply the changes. 

Part 1: VX Engine Upgrade 

Since VX components are administered via LAN 

connection, your first step in upgrading is to note the IP 

address assigned to your VX Engine. This is easily 

obtained by observing the front-panel display of your 

Engine. You may execute the upgrade using a Web 

browser on any computer residing on the LAN your VX 

is attached to. 

1) Enter IP address of your VX Engine in the 

address bar of your Web browser and press Enter. You will be asked for a 

password. 

Default username is user. 

Default password is not set – leave this field empty.

2) Once the VX Control Center web page is loaded, choose System, then Firmware 

from the menu. You will see your current firmware in the firmware list, similar to 

what’s shown in the screenshot below. 

3) Download the latest firmware package from www.Telos-Systems.com and save it 

to your computer’s hard drive. At the time of this writing, the newest released VX 

Engine version is 1.1.1-10110; the update file package is named 

1601-00512-011-vxengine-1.1.1-10110. 

4) Click the Choose File button and highlight your new firmware file using the 

navigation window that opens. Click the Open button to select the file for upload. 

5) Click the Upload button and your update package will be transferred to the VX 

Engine. After the new firmware appears in the image list, Activate and Delete 

buttons will appear next to it. Press Activate. 

After activating the new software, you’ll receive a reboot notification. Press the 

Reboot Now button. You’ll be prompted again to confirm that you wish to reboot; 

click OK and your VX engine will restart. 

The reboot will take less than one minute. Upon reboot, you will be automatically 

redirected to the VX Engine main page. If more than one minute has elapsed 

without the main page appearing, your browser settings may not allow redirects. 

Enter your VX Engine’s IP address manually.

6) Return to the System Firmware page and confirm that the new firmware has 

been activated. It will be displayed in the Firmware Information list in bold, and 

(Active) will be displayed next to it. 

Part 2: VSet Phone Upgrade 

As with the VX Engine upgrade, a PC with Web browser is 

required to update the VSet phones. To the IP address of a VSet, 

press the Menu button on the VSet and choose the Setup screen. 

1) Enter the VSet IP address in your PC’s Web browser. You 

will be asked for a user name and password. 

Default username is “user”. 

Default password is not set – leave this field empty. 

2) Download the latest firmware package from www.Telos- 

Systems.com and save it to your computer’s hard drive. At 

the time of this writing, the newest released VSet version is 

1.1.0-10148; the update file package is named 

1601-00514-002_VSet-1_1_0_10148.pkg. 

3) On the VSet’s Web page, click the Choose File button in the Firmware Upgrade 

section and highlight your new firmware file using the navigation window that 

opens. Click the Open button to select the file for upload. VSet phones have two 

“software banks” for firmware storage; new software will be loaded to the bank 

that is currently inactive. 

4) Press the Upgrade button. You will be notified that the new firmware file is 

uploading to the VSet. When done, the screen will display “Firmware 

successfully uploaded to bank n.” Press the Activate new firmware now button. 

5) The new firmware bank will be activated and the VSet will reboot. After 40 

seconds, the Web page will refresh and you will see the newly uploaded firmware 

in the Firmware Version list. 



TECH SUPPORT 

Note that you can switch between the two firmware banks using the Change bank 

button should you need to revert to an earlier version.

The way web passwords were stored was broken in previous versions, possibly causing the 

system to malfunction. This is fixed with v1.1.0, and the password will be reset after upgrading. 

Old settings are simply ignored. 

The system-wide public IP option is removed in v1.1.0 in favour of a separate setting for each 

server. Users upgrading from v1.0.x will need to set it again as needed. 

The semantics of the default domain option are changed. In previous versions setting it to a 

different value would change the server address of all lines using it. In v1.1.0 it only affects new 

lines; to change the server address for existing lines, please use the “SIP Server” option. 

Related to the above, it is possible that after upgrading, the default domain is shown as “” 

in the server list. If you experience this, please ask Support for instructions regarding how to fix it.
