Enable Telnet on VVX Devices (Telnet Commands)

Hello all

My adventurous soul have discovered a new way to check stats, settings and more things without use web interface of Polycom VVX.

You can show more information using telnet (very useful for administrators and for troublesooting). However, Telnet is disabled by default on all Polycom device. If you want to use Telnet on VVX devices, you need to activate it, but the option doesn’t appear neither the phone menu or web interface. You need to create a cfg file to enable it.

To do that, open a notepad and type the following command:

<telnet diags.telnetd.enabled=”1″></telnet>

Then, you can rename it how you want, for examble “enableTelnet” but you need to ensure that the extension of this file is .cfg

After that, you must connect with VVX web interface and import this file using “import and export” configuration.


After that, you can connect by telnet to the device. By default, the user is “Polycom” but the password is the same that you configure in your Admin user (so if you didn’t change the default password, it will be “456“). (Note! If you have a mistake introducing username or pasword, it is probably that you need to restart the phone).


NOTE! Do not forget to create another cfg file to disable Telnet after you finish your configuration (If not, you will have a very high security hole). This file must have the following command:

<telnet diags.telnetd.enabled=”0″></telnet>

When you use “import and export” configuration to disable Telnet, phone will be restarted

How you have much possibilities availables to use commands. You can find below, a list of “Polycom Telnet commands” available to adapt to your needs (also you can obtain this list typing “help” on the command prompt):
